CGovernanceManager::IsValid() returns true only if its db is successfully
initialized. If we attempt to initialize it and fail, init logic will
report to us that it failed. If we don't attempt to initialize it at all,
it will remain false.
Since fDisableGovernance is the same as not initializing it at all and
the other case where IsValid() is false is dealt with in init, we can
use IsValid() to infer if governance is enabled.
CActiveMasternodeManager no longer exists as a global variable, it is a
conditionally initialized smart pointer. If it exists, then it's in masternode
mode, no need to check if we're in masternode mode anymore.

## Additional information
* Dependency for https://github.com/dashpay/dash/pull/5982
* Unfortunately, we are stuck with using the `unique_ptr` const-ref of `PeerManager` for initializing {`CJ`, `LLMQ`}`Context` due to some unit tests depending on Dash-specific entities but based on a testing setup that doesn't initialize `PeerManager` (specifically `validation_chainstatemanager_tests`, which uses `ChainTestingSetup`, as opposed to `TestingSetup`, which initializes `PeerManager`).
Attempting to dereference it earlier will result in crashing (see CI pipeline [here](https://gitlab.com/dashpay/dash/-/pipelines/1245924304))

Since the nChainTx is now unused in the metadata, it should be removed

faecb74562d012a336837d3b39572c235ad2eb9d Expose integral m_conn_type in CNodeStats, remove m_conn_type_string (Jon Atack)
Pull request description:
Currently, strings are stored for what are actually integral (strong) enum types. This is fine, because the strings are only used as-is for the debug log and RPC. However, it complicates using them in the GUI. User facing strings in the GUI should be translated and only string literals can be picked up for translation, not runtime `std::string`s.
Fix that by removing the `std::string` members and replace them by strong enum integral types.

fe3d17df04decc4e856121eb311636977d60f80f net: ignore block-relay-only peers when skipping DNS seed (Anthony Towns)
Pull request description:
Since #17428 bitcoind will attempt to reconnect to two block-relay-only anchors before doing any other outbound connections. When determining whether to use DNS seeds, it will currently see these two peers and decide "we're connected to the p2p network, so no need to lookup DNS" -- but block-relay-only peers don't do address relay, so if your address book is full of invalid addresses (apart from your anchors) this behaviour will prevent you from recovering from that situation.
This patch changes it so that it only skips use of DNS seeds when there are two full-outbound peers, not just block-relay-only peers.

79c02c88b347f1408a2db307db2654917f9b0bcc Randomize message processing peer order (Pieter Wuille)
Pull request description:
Right now, the message handling loop iterates the list of nodes always in the same order: the order they were connected in (see the `vNodes` vector). For some parts of the net processing logic, this order matters. Transaction requests are assigned explicitly to peers since #19988, but many other parts of processing work on a "first-served-by-loop-first" basis, such as block downloading. If peers can predict this ordering, it may be exploited to cause delays.
As there isn't anything particularly optimal about the current ordering, just make it unpredictable by randomizing.

8050eb43bf15501e33ec5312918d926e47e4fc8d script: fix spelling linter raising spuriously on "invokable" (Jon Atack)
Pull request description:
"invokable" is a valid word that means to be callable, but the linter is raising on it:
```
$ test/lint/lint-spelling.sh
contrib/guix/guix-attest:18: invokable ==> invocable
contrib/guix/guix-clean:18: invokable ==> invocable
contrib/guix/guix-verify:18: invokable ==> invocable
^ Warning: codespell identified likely spelling errors. Any false positives? Add them to the list of ignored words in test/lint/lint-spelling.ignore-words.txt

## Additional Information
When building Dash with `clang-16`, I use the following `CXXFLAGS`:
```
-Werror -Werror=reorder -Werror=thread-safety -Wno-unused-command-line-argument -Wno-deprecated-builtins -Wno-deprecated-volatile -Wno-ambiguous-reversed-operator -Wno-deprecated-enum-enum-conversion
```
The explanations of the `-Wno*` flags are as follows:
| Argument | Reason |
| -------------------------------------- | ------------------------------------------------------------ |
| `-Wno-unused-command-line-argument` | Lingering use of `-static-libstdc++`, a GCC-ism that isn't recognized as a valid argument in Clang (no longer an issue thanks to https://github.com/dashpay/dash/pull/5958, thanks knst!) |
| `-Wno-deprecated-builtins` | Due to usage of [deprecated builtins](2dacfb08bd/src/bench/nanobench.h (L104-L110)) in `nanobench` that exist even in the [most current version](a5a50c2b33/src/include/nanobench.h (L115-L121)) (see below) |
| `-Wno-deprecated-volatile` | The detection code for C++20 in the CI image (based on Ubuntu `focal`) relies on deprecated volatiles (see below) |
| `-Wno-ambiguous-reversed-operator` | Due to an ambiguous operator in a Dash unit test ([source](2dacfb08bd/src/test/fuzz/addrman.cpp (L145))) (see below) |
| `-Wno-deprecated-enum-enum-conversion` | Due to key combination code in Dash Qt ([source](2dacfb08bd/src/qt/bitcoingui.cpp (L376))) (see below) |

This pull request removes the need for the last two `-Wno*` flags, removes some leftover `boost::`{`function`, `lexical_cast`} usage and some `gArgs` usage where a local variable would be more applicable.
Additionally, in some builds, there is an deprecation warning (`-Wdeprecation`) for using `[=]` and relying on its implicit capture of `this` (see below), this can be seen during GCC builds but not Clang builds and correspond to a proposal to the C++20 standard ([proposal](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0806r2.html)).
It has also been mentioned at https://en.cppreference.com/w/cpp/language/lambda, "The implicit capture of `*this` when the capture default is `=` is deprecated. _(since C++20)_". This has also been remedied as part of this PR.
