Previous commit missed a few places where `pkg_resources` module was
used.

chore(developer): consolidate external links in Developer messages

docs(developer): kmc-ldml api documentation

fix(developer): hint text special characters

fix(developer): move osk.ts from developer-utils to kmc-kmn

Fixes #10372.

auto: increment beta version to 17.0.282

Establishes keyman-urls.ts as a single place for any links to external
websites.

I searched all .ts files in Keyman Developer source and replaced
references to websites with function calls here. Note that the names of
individual functions within this class can be easily changed as needed,
as the hard part was the consolidation.

Merge pull request #10906 from keymanapp/chore/developer/10889-deploy-compiler-messages-to-help-site

chore(developer): deploy compiler messages to help site

fix(ios): cross-paragraph keyboard rules

chore(linux): Update debian changelog

auto: increment beta version to 17.0.281

Relates to #10207.

Note: reduces the API surface by removing members which should be
internal. Fixes a few minor typos in other API docs. Adds missing docs
for kmc-kmn also.

api-extractor returned the following error:
```
ERROR: The "export * as ___" syntax is not supported yet; as a workaround, use "import * as ___" with a separate "export { ___ }" declaration
```

Fixes #10889.

This involved a bit more refactoring to help-keyman-com.sh in order to
allow for multiple paths to be uploaded.

I opted _not_ to move the entire Keyman Developer documentation into
this repository, partly because a number of pages are still in PHP
rather than Markdown.

feat(windows): move the code kmshell.dpr to unit so that only the includes are in dpr 

fix(android): handle surrogate pairs in selection range indexing

test(developer): kmc unit test infrastructure messages

Fixes #10872. Modifies #10845.

developer-utils is also used by server. Because osk.ts depends on
common-types, this introduced a transitive dependency for
developer-utils. Packaging server for deployment as part of Keyman
Developer is fragile and we need to hand-code our internal dependencies,
as npm bundling struggles with in-repo dependencies. So we need to avoid
introducing extra dependencies into developer-utils at this time.

It turns out that osk.ts is used by kmc-kmn and kmc-analyze. kmc-analyze
already has a dependency on kmc-kmn, so it makes sense to put it there.

feat(developer): adds kmc message command

fix(ios): context-initial diacritic handling

refactor(developer): reorganize messages for adding details

refactor(developer): cleanup kmn compiler message namespaces

docs(developer): kmc-kmn api documentation and some message documentation

Merge pull request #10819 from keymanapp/chore/common/9843-keyman-touch-layout-schema-restrictive-layer-id

chore(common): loosen .keyman-touch-layout schema layer id requirements

fix(developer): make sure scroll bar appears when needed in global welcome

auto: increment beta version to 17.0.280

It isn't enough to have the package as build dependency, we also have to
list is in the binary package or in the `install_requires` list in
`setup.py`. This change also adds other missing python modules to
`install_requires` so that things work correctly if building/installing
from source.

chore(resources): update to latest ldml: xmlns, uset
