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.

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
