Fixes #9349.

Also fixes git attributes for khmer_angkor.js test fixture

Merge branch 'chore/developer/move-keyman-targets-to-common' into feat/developer/introduce-kmc-keyboard-info

Fixes missing components of the kmc-keyboard-info compiler and
integration into kmc. Lots of cleanup making sure that the compiler
actually generates expected output against the keyboards repository.

Adds kmc-keyboard-info module and a basic unit test for it. Integration
into kmc is next step.

Also adds unit test. Prep for use in kmc-keyboard-info.

Fixes #9305.

Merge branch 'fix/developer/9296-9297-9298-9299-9300-compiler-warning-tweaks' into fix/developer/9302-double-add-of-keyboard_info

Fixes #9302.

Fixes #9300.

Fixes #9299.

Fixes #9298. Previous commit partially fixed this as well.

Throws in: warning colour changed to orange to differentiate from line
number colour.

Fixes #9297.

Fixes #9296.

208A in kmcmplib is the awkwardly-named CWARN_Info. We now have an
'info' severity in kmc, so this tidies that up (we can keep the same
flag in kmcmplib for now).

Fixes #9288.

Tweaks a couple of unit tests to ensure callbacks are available, and
stops masking exceptions in one test with `doesNotThrow`... if it's
gonna throw then the test is gonna go bang anyway.

Fixes #9286.

Refactors the use of path and fs into the standard kmc callbacks pattern
and adds `callbacks.fileSize()`, which is needed for populating the
metadata file.

Turns on eslint test for node dependencies for kmc-model-info.

Merge branch 'feat/developer/add-model-info-keyboard-info-to-kmc-build-activities' into chore/developer/9272-work-around-experimental-json-modules

Merge branch 'feat/developer/kmc-model-info-tests' into feat/developer/add-model-info-keyboard-info-to-kmc-build-activities

Fixes #9272.

Adds ability to build .model_info and .keyboard_info files to kmc. Note
that .keyboard_info building is currently a stub as the .keyboard_info
compiler has not yet been translated to TypeScript, which will come in a
subsequent PR.

Note that .model_info and .keyboard_info builds depend on the project
loader, as they reference both keyboard and package source files when
constructing the metadata files.

Also:
* Fixed a deep reference to KeymanDeveloperProjectFile.
* Split the project loader into a utility unit.
* Marked the .kpj fileType field as deprecated, as it is easily
  extrapolated from the filename, with the aim to remove it entirely
  from version 2.0 projects.

Establishes a baseline unit test for kmc-model-info, in preparation for
integration into kmc build.

Fixes #9274.

Fixes #9162.

Adds support for `@files.txt` parameters in kmc. Files listed in this
file, separated by line breaks, will be added to the input file list,
relative to the path of files.txt.

The file can include comments in lines starting with '#' and ignores
whitespace before and after each filename.
