Fixes #8998.

kmc-kmn messages were broken down into sub-namespaces, but the range
overlapped the reserved namespace mask range. Fixed the message values,
added a new test to the verifyCompilerMessagesObject function to verify
that messages don't creep outside their namespace, and defined new
masks (in CompilerErrorSeverity enum... hmm) to help.

I opted to remove the leading `0` in the messages for kmc-kmn as I had
to correct a number of them anyway, but not the messages in remaining
units at this time (it's not an error, but just slightly misleading as
we only have 12 bits, not 16 to play with).

It is safe to reassign these messages as they were only assigned in 17.0
alpha.

Fixes #8960.

Will need a further minor refactor in the future for kmc-kmw as it also
uses some of these same error codes.

Enables eslint checks for eslintNoNodeImports for kmc-kmn. Also enables
linting for kmc-model-info, but does not enable eslintNoNodeImports on
it at this time.

Relates to #8959.

This change fixes this and also extract some additional methods.
