Pull request description:
Remove no longer needed UBSan suppressions (issues fixed). Add documentation.
This PR is the CI-only subset of #17208 (which touches code).
From a fuzzing perspective it would be really nice to be able to run UBSan with as few suppressions as possible :)

9d933ef9191417b4b7d29eaa3c3a571f814acc8e prevector: avoid misaligned member accesses (Anthony Towns)
Pull request description:
Ensure prevector data is appropriately aligned. Earlier discussion in #17530.
**Edit laanwj**: In contrast to #17530, it does this without increase in size of any of the coin cache data structures (x86_64, clang)
| Struct | (size,align) before | (size,align) after |
| ------------- | ------------- | ------- |
| Coin | 48, 8 | 48, 8 |
| CCoinsCacheEntry | 56, 8 | 56, 8 |
| CScript | 32, 1 | 32, 8 |

958e1a307e streams: Remove unused seek(size_t) (practicalswift)
Pull request description:
Fix broken `streams_vector_reader` test. Remove unused `seek(size_t)`.
Before this change the test `streams_vector_reader` triggered an unintended unsigned integer wraparound. It tried so seek using a negative value in `reader.seek(-6)`.
Changes in this PR:
* Fix broken `VectorReader::seek(size_t)` test case
* Remove unused `seek(size_t)`
