fix(linux): Replace deprecated `pkg_resources` module with `packaging.version`

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

Refreshes all of the public API header documentation so we have a single
source for the documentation -- the keyman_core_api.h header. A lot of
reformatting but very little change in terms of content.

This is converted into Markdown by api-header-extractor, and the results
can be copied to help.keyman.com.

Will only do the main keyman_core_api.h for v17 release, in interests of
time. The other headers are primarily internal only and have many
deprecated functions also.

Will also leave the full automation of the documentation generation to a
future PR. The script will be there but it won't run during build for
now.

chore(mac): clean up code obsoleted by core

auto: increment beta version to 17.0.291

Because exitProcess is async, static analysis of the function does not
show process termination, even though it returns Promise<Never>. This
can lead to compiler warnings when it gets confused about missing return
values. So have moved to always returning the value from exitProcess,
even though it will never actually return!

auto: increment beta version to 17.0.290

fix(common): add unit test for --debug flag for builder

Fixes #11002.

The fields `<RelatedPackages/>` and `<Examples/>` should not be emitted
if they have no content, to improve file backward-compatibility.

fix(developer): add code coverage for ERROR_FontFileCannotBeRead due to difficulty in forcing this error
