747cd17404832604c50d03d58e11ba816bb229f7 build: no-longer fail default configure if BDB isn't available (fanquake)

Pull request description:

  Inline with moving to descriptor (sqlite) wallets by default for 0.23,
  this adapts the build system so that a default `./configure` invocation
  no-longer fails if BDB isn't present. Currently, if configure is run
  with no options, and no BDB is present, we'll fail with:
  ```bash
  checking for Berkeley DB C++ headers... no
  configure: error: libdb_cxx headers missing, Bitcoin Core requires this library for BDB wallet support (--without-bdb to disable BDB wallet support)
  ```

  If descriptor wallets are to be the default, this behaviour no longer
  makes sense, as a builder should be able to configure and build, to use
  a wallet, without BDB installed, and without passing additional
  arguments, i.e `--without-bdb` or `--with-incompatible-bdb`, to
  configure.

  With this change, running configure will no-longer fail, but will
  instead print:
  ```bash
  checking for Berkeley DB C++ headers... no
  configure: WARNING: libdb_cxx headers missing
  configure: WARNING: Bitcoin Core requires this library for BDB (legacy) wallet support
  configure: WARNING: Passing --without-bdb will suppress this warning
  checking for sqlite3 >= 3.7.17... yes
  checking whether to build wallet with support for sqlite... yes
  ```
