Replaces kmcomp's package installer build infrastructure. While this is
mostly legacy, package installers are still used in adhoc distribution
scenarios, so we need to continue to support with the new kmc.

The package installer is a Windows self-extracting zip archive. The user
is expected to find setup-redist.exe and keymandesktop.msi themselves,
from the Keyman Developer release files. They are not included with
Keyman Developer, but are available as standalone downloads from
https://downloads.keyman.com/windows/.

`kmc build` has been updated to include two subcommands:
* `kmc build ldml-test-data`
* `kmc build windows-package-installer`

Both of these subcommands are a little long, but the use cases for them
are fairly narrow, so I believe this is okay. `kmc build-test-data` has
been removed, as `kmc build ldml-test-data` replaces it.

Removes kmcomp.dpr, related source, compilekeymanweb.pas, and related
unit tests.

Cleans up a couple of bits and pieces around kmc in order to help tests
to pass, and updates some tests that had legacy code in them
(particularly missing &TARGETS stores).

Consolidates the outFile parameter that was duplicated in kmc-kmn.

Also removes unused FSilent flag (was always False).

First step of integration of kmc into TIKE, establishing base classes
and replacing the lexical model compiler wrapper with them.

Adds logFormat of tsv vs formatted for kmc, in order to allow for
"porcelain" style log formatting when we interop with TIKE.

Works around npm/cli#3466 when bundling internal dependencies using the
bundleDependencies package.json property.

This change works in tandem with the npm pack/publish process -- when we
run `developer/src/kmc/build.sh publish` (or `pack`), we end up with
`npm version` stomping on all our package.json files, so the repo is
dirty after this. We need a copy of the top-level package.json before
this stomping happens, in order to get a simple map of the location of
each of our internal dependencies, from the `dependencies` property (it
would be possible to figure this out with a lot more parsing of
our package.json files, but this is simpler).

This means, in future, we should avoid publishing our internal
dependencies such as those under common/ to npm, as they serve no
practical purpose there.

Adds support for calculating isRTL and license fields in .model_info
compiler.

Also:
* establishes @keymanapp/developer-utils shared module
* moves license validation into @keymanapp/developer-utils
* refactors kmc-model-info to a class and general cleanup

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).

Moves responsibility for loading .kps into kmc-keyboard-info, away from
the caller, and removes other fields with kmc-keyboard-info can
calculate by itself.

Have not moved project parsing into kmc-keyboard-info, because that's a
bigger job, as currently that is mostly happening within kmc itself. A
project for a future version I think.

Also fixes a file reference issue in kmpJson.options, where paths were
stripped too early in the process.

Removes a now-irrelevant unit test for keyboard_info.

TODO: markdown to html during the keyboard_info build.

Relates to #9351.

Adds support for building a .keyboard_info file without having source
.keyboard_info file:

* Constructs a default source .keyboard_info in memory
* Hints if license is missing
* If LICENSE.md is present, verifies it matches the MIT license text
* Adds project option to turn on or off metadata generation. This will
  default to False for version 1.0 projects, and to True for version 2.0
  projects. This means that the keyboard repository will need a PR to
  enable metadata generation for existing projects in the repository,
  but this is important to avoid breaking builds for existing projects
  that are not in the repository.
* Turns on additional c8 coverage for kmc projects

* Removes font size
* Restricts font source to array
* Removes example
* Add examples
* Loosen structure of KeyboardExample

Adds license file to .kps, kmp.json, kmc-package, package editor, and
new project templates. The intent is for LICENSE.md to be the file used,
and for any keyboards on keymanapp/keyboards, it should always be a
standard MIT license.
