Fixes#10487.
In Keyman Developer's wrapper of kmc, we now accept
`--enable-source-maps` as the first parameter to pass to kmc. We do not
enable source maps by default because they have a performance penalty.
Removes all references to source .keyboard_info and .model_info files in
the kmc compiler and types. Updates the model info compiler to support
building purely from model sources (isRTL, license fields are TODO).
Deploy kmc as an ES module, forced now by top-level await that we use in
the sentry load.
Moved NodeCompilerCallbacks to same util folder as schemas are found in,
to avoid rewriting schema loading with imports in this PR. It belongs
better there than messages/ anyway.
Distributed files are now .mjs. Removed --enable-source-maps from
launchers as logging will be managed with sentry anyway.
Fixes#7408.
For kmc*.cmd, enables source maps. If you are running kmc from node on
your own system, you may need to enable source maps in other ways.
Note that error reports should be going through to Sentry, and source
maps should already be used for those.
Fixes#7237.
Full clean, configure and build will be required for Core, Developer
after this change.
kmc is much less unwieldy a name than kmldmlc, and becomes our platform
for future compiler integration. Start of implementation for #5283 also.
