fix(developer): schema conformance for model package compiler

fix(developer): Improve stability of named code constants

auto: increment beta version to 14.0.251

fix(common/resources): Fix help.keyman.com path for CI

Fixes #2998.

Three parts to this:

* The package compiler will now give a warning if a keyboard in a
  package does not contain any language metadata.

* Removed old canonicalization check during compile which is now handled
  better in `TPackageInfoRefreshKeyboards`.

* Reduced non-canonical BCP 47 tag warnings in
  `TPackageInfoRefreshKeyboards` to "info" so they do not block the
  build.

Point 3 above is one part of the outcome of our BCP 47 discussion at:
https://docs.google.com/document/d/1N5CkTX7tlLlmUB9Mbd-LblY1ch1e642XxlTasC_WE_Q/edit#heading=h.fiy983iliay5

chore(ios/app): Adjust help titles for installing custom dictionaries

Fixes #2740.

The definitions for several of the combined modifiers was incorrect,
which led to a mismatch when attempting to import those layers from a
visual keyboard into the touch layout editor.

fix(web): mnemonic keystrokes w FF keymapping

Fixes #3199.

Ensures that the model package compiler passes schema validation for
kmp.json. Three problems were corrected:

1. `followKeyboardVersion` is a source-only property; it should not be
   in deployable kmp.json.
2. `copyLocation` should have been a number not a string (in XML
   everything is a string... but JSON has more control here)
3. `fileType` is a source-only property; it also should not be in
   deployable kmp.json.

I have checked that the resulting files validate against the package
kmp.json schema version 1.1.0 defined at
https://github.com/keymanapp/api.keyman.com/blob/master/schemas/package/1.1.0/package.json.

None of these fixes should impact the use of these packages in target
apps. `followKeyboardVersion` and `fileType` are used only in the source
at package development time, and `copyLocation` is unused (and should be
eliminated from Keyman altogether in the future).

Fixes #4423.

Using a named character constant with a store name that included
characters outside ascii could cause kmcmpdll to crash with an assertion
failure.

This fix allows store names defined in the .kmn file to use characters
outside ascii.

Note that more work needs to be done on which characters are acceptable
to use, as this is somewhat implementation-specific according to the C++
specification for `iswalpha`.

Added a test case to verify various named code constant examples.

Also removes dead code for `IsCJKUnifiedIdeograph` as this was never
used and somewhat pointless in any case.

NamedCodeConstants.cpp could stand to be rewritten using `std::map` or
equivalent. Current implementation is pretty icky.

fix(windows): Handle Caps Lock event correctly from TIP

Fixes #4221.

When the Keyman Developer IDE calls out to the lexical model compiler,
it receives UTF-8 compiler message strings back but they are treated as
Windows-1252 strings. This fixes that.

Fixes #4451.

If sentry.dll is missing, we should continue without error reporting,
rather than crashing out.

Fixes #4525.

This is a regression from #4468, which inadvertently added modifier
checks for `VK_CAPITAL` and `VK_NUMLOCK`, when it should not have done
so, as the flag was then being reset when the key was released rather
than toggled.

`ProcessModifierChange` pretended that it could handle `VK_CAPITAL` and
`VK_NUMLOCK` but it would never have worked, and the other caller (the
GetMessage hook) never passed those key events through, only Shift, Ctrl
and Alt, so that's now what the TIP handler does as well.

This leaves the rest of the fix from #4468 in place as that appears
correct.

I took the opportunity to move a repeated function declaration into
keyman64.h.

Fixes #4445.

When upgrading from 11.0, 12.0 or 13.0, Keyman needs to re-register the
TIPs so that we use the new registration model for 14.0. However, if we
do this on a 14.0 version install, we end up registering TIPs for every
single suggested language for a keyboard, which is definitely not what
we want.

This fix simply looks to see if we have a 14.0-style installation
already, as evidenced by the presence of a `Transient Language Profiles`
key, and if found, does not continue the 11to13 upgrade process.
