Fixes#8795.
Relates to #9090.
Cleans up and makes consistent compiler messages in kmc, and related
unit tests.
Adds support for colorized messages.
After installing chalk for ansi coloring in kmc, @types/node needed to
be brought in sync with the Typescript version, per the suggestion of
checking against `npm dist-tags @types/node`,found in a discussion at
https://github.com/DefinitelyTyped/DefinitelyTyped/discussions/64262#discussioncomment-4905069
Additional tidying up includes:
* Deprecating a set of functions in compiler-interfaces, bringing them
together under a new CompilerError class.
Separating CompilerErrorSeverity and CompilerErrorMask enums.
* Making CompilerError.formatEvent (formerly compilerEventFormat) print
messages in the same format as NodeCompilerCallbacks (sans coloring).
* Adding a wrapper class for CompilerCallbacks that manages the filename
reporting, used currently exclusively by kmc itself.
