Relocates the keyboard-repo fixtures so we can add other local fixtures
for unit tests.

Relates to #8493.

* Removes kmcmplib calls from kmcmpdll (now that we have kmc)
* Removes old kmcmp_CompileKeyboardFile and
  kmcmp_CompileKeyboardFileToBuffer functions in preference for a much
  cleaner kmcmp_CompileKeyboard function
* Removes json validation helper from kmcmplib (we'll use js-native
  json schema validation instead)

This change means that we no longer need to keep compfile.h consistent
between kmcmplib and kmcmpdll. This will simplify upcoming refactoring
of kmcmplib.

kmcmplib no longer writes files, but it does still read them. The next
refactor will move file load responsibility into the caller.

This moves the remainder of the WASM interfaces in kmcmplib to using
emscripten bind. It is a little bit of a step backwards at present for
parseUnicodeSet, because I've changed the output buffer type to an int
for the purposes of simplifying the binding just now. But that can be
improved later, and at least we are consistent with the binding methods.

Next step is to move the filesystem access out of kmcmplib.

The `SetError` macro emitted `return FALSE;` which was confusing for
reviewing code flow. Replaced with explicit `AddCompileMessage()` and
`return FALSE;`.

FILE_KEYBOARD is a structure used in multiple libraries and languages.
It is passed around between kmcmplib, kmcmpdll, and kmcomp, with three
separate definitions (kmcmplib/compfile.h, kmcmpdll/compfile.h, and
kmcomp/compile.pas). These duplicate definitions must be maintained for
now because of type issues between the legacy kmcmpdll and kmcmplib,
which means that the definitions must be kept in sync.

Because FILE_KEYBOARD_EXTRA has a C++ class in it, it will be
initialized in CompileKeyboardHandle rather than in the caller, so
FILE_KEYBOARD.extra is now a pointer rather than a struct.

When original kmcomp and kmcmpdll are eventually removed, these
duplications will disappear and some of the memory management and
lifecycle will become easier to manage.

This starts the refactor of the .kmn compiler interfaces for WASM,
moving more file writes into typescript and out of the compiler. Adds a
cleaner binding and structures for passing compile metadata back to
typescript for additional build steps (e.g. kvk, js builds).

Will rebase the Typescript-based KMW compiler onto this so it can start
to benefit from the refactoring.

* Fixes a minor issue with loading a .kvks file with an empty flags set.
* Adds a writeFileSync method to the compiler callback interfaces.
* Adds an e2e compiler test to verify that .kmx and .kvk are both
  correctly compiled.

Stage one of the kmcmplib filesystem refactoring, as we move to writing
to buffers and allowing caller to write to disk. Moves responsibility
for writing data out of WriteCompiledKeyboard and into
kmcmp_CompileKeyboardFile. This means that there are now no file writes
in Compiler.cpp, except for the temp UTF16fromUTF8 (which I will also
change to a in-memory buffer "real soon now").

Note that responsibility for writing in kmcmp_CompileKeyboardFile is
very much temporary as we'll move it out of the library altogether in
a subsequent commit.
