Relates to #2761.

kmc now supports passing in a folder and building all Keyman source
files found in the folder, even if a .kpj is not present in the folder.

If a .kpj file exists, `KeymanDeveloperProject/Options/Version` will be
checked to determine behaviour. If this field is missing or "1.0", then
the classical behaviour persists.

If the Version field is "2.0", the `Files` key is ignored, and .kmn,
.xml, .model.ts, and .kps files under `sourcePath` are enumerated and
added to the in-memory project for build.

If a .kpj is not present in the folder, a virtual project is constructed
in memory with the following defaults:

* `version`: `2.0`
* `buildPath`: `$PROJECTPATH/build`
* `sourcePath`: `$PROJECTPATH/source`
* `compilerWarningsAsErrors`: `false`
* `warnDeprecatedCode`: `true`
* `checkFilenameConventions`: `true`

It is still considered an error to include both a keyboard and a model
in the same file, but a version 2.0 project will not incl...

Adds support for building .kpj projects. Required minor tweak to kmcomp
to allow it to build both .kmx and .js from .kmn command line.
Currently, calls kmcomp.exe to build .kmn files, until we support a
cross-platform kmc-kmn C++ project.

auto: increment master version to 17.0.58

chore(android/app): Revert #8291

- add check for missing flicks
- remove a tray #include

chore(common): ldml TODO-LDML cleanup 🙀  #8069

auto: increment master version to 17.0.57

chore(linux): Improve detecting presence of test files

Adds basic support for compiling .model.ts files using kmc-model to kmc.

feat(common): adds warning if described output does not exist

This reverts commit dc7603a9.

With recent work the location where we generate the test files
changed, but the test setup script didn't completely work.

fix(linux): Fix upload in packaging GHA

Adds basic support for compiling .kps files using kmc-package to kmc.

Uses existing kmcomp.exe to build .kmn files. Requires kmc to be in a
subfolder of the Keyman Developer binary folder.
