Subject: [PATCH v1] testwrap: support EXTRA_REGRESS_OPTS environment variable

From: Bertrand Drouvot <[email-masked]>

With autoconf, EXTRA_REGRESS_OPTS can be used to pass additional flags to
pg_regress, pg_isolation_regress, and pg_regress_ecpg. For example:

EXTRA_REGRESS_OPTS="--use-existing" make installcheck

There was no meson equivalent. The TESTS environment variable could not be
used for this purpose because setting it replaces the schedule entirely,
so passing only flags (e.g., TESTS="--use-existing") resulted in no tests
being run.

Add support for EXTRA_REGRESS_OPTS in testwrap. When set, its contents are
appended to the test command for regress, isolation, and ecpg test types,
matching autoconf behavior.

This enables running the full schedule with extra pg_regress options, like:

EXTRA_REGRESS_OPTS="--use-existing" meson test --setup running --suite regress-running
