feat(developer): touch layout compiler for LDML 🙀

chore: merge master into feature-ldml A17S7 🙀

feat(core): ldml rename key2 to keys 🙀

* core/build.sh -- accept feature-ldml changes (remove call to get_builder_OS)
* developer/src/kmlmc/build.sh -- delete file
*	linux/debian/rules -- accept master changes, fixup call to core/build.sh
*	linux/ibus-keyman/tests/Makefile.am -- accept master changes, fixup call to core/build.sh
*	linux/scripts/build.sh -- accept master changes, fixup call to core/build.sh
*	linux/scripts/reconf.sh -- accept master changes

auto: increment master version to 17.0.54

chore(linux): Cleanup GHA

`deb_signing` only runs for release builds, so it doesn't make
sense that `set_status` (which only runs for non-release builds)
depends on it.

chore(linux): Improve deb-packaging GHA

This change eliminates the need to checkout the Keyman source repo
on the self-hosted runner. The checkout previously timed out, and
the only reason we need it was the `apt-install` action. So now
we directly call `apt install` instead of using the action.

fix(linux): Collect consecutive backspaces

chore(windows): Remove old Kannada setup strings

This updates our meson min version on Windows to 1.0, which means that
we can avoid having Visual Studio on the path, as meson can find it
anyway. With this change, we can eliminate the batch-wrapper for the
build, significantly improving build performance and simplifying the
scripts.

This also adds a change to disable tests for dependency builds of core,
along with the `--no-tests` command line option for doing builds without
tests.

Minor cleanup includes eliminating various warnings from meson.build
files, and standardizing WASM cross-platform build options for Windows.

- So in summary, since before #7532 basically keys was restructured, and the old 'keys' was moved into 'keys.kmap'.

#8069

feat(core): ldml: implement xml test cases 🙀

chore: ldml: merge from master 🙀

auto: increment master version to 17.0.53

When using Wayland `im-wayland.so` (which is part of libgtk) gets
loaded into the client app instead of `im-ibus.so`. This means that
our ordered output doesn't work with Wayland.

This change works around a problem with keyboards that use multiple
consecutive backspace actions. Because method calls get processed
asynchronously some backspaces get lost. In clients that support
surrounding text we can count the consecutive backspaces and then
do one call to delete surrounding text with the appropriate number
of characters.

This can be tested with "Khmer Angkor" keyboard by typing `xEjmr`,
or with "Vedic Sanskrit Devanagari Phonetic (ITRANS)" keyboard by
typing `shrI`.

Part of #4273.
