Merge bitcoin/bitcoin#23137: Move-only: bloom to src/common

fa2d611 style: Sort (MarcoFalke)
fa1e5de scripted-diff: Move bloom to src/common (MarcoFalke)
fac303c refactor: Remove unused MakeUCharSpan (MarcoFalke)

Pull request description:

  To avoid having all files at the top level `./src` directory, start moving them to their respective sub directory according to bitcoin/bitcoin#15732.

  `bloom` currently depends on libconsensus (`CTransaction`, `CScript`, ...) and it is currently located in the libcommon. Thus, move it to `src/common/`. (libutil in `src/util/` is for stuff that doesn't depend on libconsensus).
