[cmake] Support running extra clang tool tests without static analyzer

Support running the extra clang tool tests when the static analyzer
is disabled. Disable the relevant clang-tidy tests and one include-fixer
test that require it to work.

Previously, the tests were disabled entirely with
CLANG_ENABLE_STATIC_ANALYZER being false. Now, the tests are being
enabled and the relevant tests are excluded and marked unsupported
appropriately.

In order to disable clang-tidy tests, the whole test directory is added
to the exclude lists, to avoid having to explicitly add 'REQUIRES' line
to every single test. If the other solution is preferable, I can update
the patch.

The yamldb_plugin include-fixer test is also updated to be disabled
without static analyzer. It fails in that case because clang is not
outputting a replacement suggestion -- but I don't know the exact
reason why it does not do that.
