David Malcolm 1a2c62212b diagnostics: convert HTML output test plugin to 'experimental-html' sink [PR116792] ...

In r15-3752-g48261bd26df624 I added a test plugin that overrode the
regular output, instead emitting diagnostics in crude HTML form.

In r15-4760-g0b73e9382ab51c I added support for multiple kinds of
diagnostic output simultaneously, adding
 -fdiagnostics-add-output=DIAGNOSTICS-OUTPUT-SPEC
 -fdiagnostics-set-output=DIAGNOSTICS-OUTPUT-SPEC
for adding/changing the kind of diagnostics output, supporting
"text" and "sarif" output schemes.

This patch promotes the HTML output code from the test plugins so
that it is available from "-fdiagnostics-add-output=", using a
new "experimental-html" scheme, to allow simultaneous text, sarif
and html output, and to make it easier to experiment with.  The
patch adds Python-based testing of the emitted HTML.

The patch does not affect the generated HTML, which is still crude, and
not yet ready for end-users.  I hope to improve it in followups.
