  [UpdateTestChecks] Re-add --filter and --filter-out options

Re-add filtering options with fixes for failed tests.  We were not passing the
is_filtered argument in all check generator calls in update_cc_test_checks.py

Enhance the various update_*_test_checks.py tools to allow filtering the tool
output with regular expressions.  The --filter option will emit only tool output
lines matching the given regular expression while the --filter-out option will
emit only tools output lines not matching the given regular expression.  Filters
are applied in order of appearance on the command line (or in UTC_ARGS) and the
first matching filter terminates the search.

This allows test authors to create more focused tests by removing irrelevant
tool output and checking only the pieces of output necessary to test the desired
functionality.
