branchcache: rework the `filteredhash` logic to be more generic

We now have a more flexible `key_hashes` tuple. We duplicated various logic in
the V2 and V3 version of the cache as the goal is to start changing the logic
for V3 in the next few changesets.

= Mercurial 6.5.3 =

 * "hgweb: pass strings in WSGI environment correctly from wsgicgi"
 * "perf: introduce more cache invalidation option in perf::tags"
 * "perf: add a `--clear-fnode-cache-rev` argument to perf::tags"
 * "perf: add a --update-last flag to perf::tags"
 * "blackbox: add a option to duplicate output to stderr too"
 * "tags: avoid expensive access to repo.changelog in a loop"
 * "revlog: fix a bug where NULL_NODE failed to be resolved to NULL_REV"
 * "httppeer: fix static-http: scheme autodetection (issue6833)"
 * "tests: backed out changeset 8037ddacad47"
 * "stream-clone: fix a crash when a repo with an empty revlog is cloned"
 * "censor: accept censored revision during upgrade"
 * "revlog: avoid opening and closing the file for each cloned revision"

= Mercurial 6.5.2 =

 * hgweb: encode WSGI environment using the ISO-8859-1 codec
 * rhg: fix the bug where sparse config is interpreted as relglob instead of glob
 * gpg: fix an UnboundLocalError whenever using --force
 * transaction: fix __repr__() and make the default name bytes
 * setup: make the error "Unable to find a working hg binary" more informative
 * tests: avoid test environment affecting setup.py
 * run-tests: detect HGWITHRUSTEXT value

= Mercurial 6.5.1 =

 * A bunch of improvements to Python 3.12 compatibility
 * repoview: fix the filter created by `extrafilter`
 * Improve portability of the test suite
 * fncache: fix a bug that corrupts the fncache after transaction rollback
 * revlog: fix the naming scheme use by split temporary file
 * perf: fix perf::tags
