ci: temporarily disable the Perl TAP tests

While iterating on the Python pytest port, run only the pytest tests: the
Perl TAP tests double the run time and disk usage (the macOS runner has
been hitting "No space left on device").  tap_tests and pytest are
independent meson test kinds, so -Dtap_tests=disabled skips the Perl tests
while -Dpytest=enabled keeps the Python ones.  The Linux meson jobs
configure with MESON_COMMON_PG_CONFIG_ARGS and otherwise let features
auto-detect, so they do not pick up the setting from MESON_COMMON_FEATURES;
pass -Dtap_tests=disabled explicitly in their meson setup commands.

This is a temporary CI-only change to be reverted before the work is
finalized.
