I renamed 'Meson Auto' as 'Meson Auto Feature Detection' in v5.

Subject: [PATCH v5 1/3] ci: Remove PG_TEST_EXTRA from NetBSD and OpenBSD

PG_TEST_EXTRA environment variable is already set at the top level.
NetBSD and OpenBSD tasks will use this top level PG_TEST_EXTRA as
default.

Subject: [PATCH v5 2/3] ci: meson: Explicitly enable meson features

By default, Meson silently disables features it cannot detect, which can
lead to incomplete builds. Explicitly enabling these features causes the
build to fail if they are missing, making such issues visible early.

These features are explicitly enabled for all meson tasks, except:
SanityCheck: uses almost no dependencies.
Windows - VS: has fewer dependencies than listed here, so defines its
own.
Linux: uses the 'auto' feature option to test meson's automatic
behavior.
