ci: debian: Switch to Debian Trixie release

Debian Trixie CI images are generated now [1], so use them with the
following changes:

- detect_stack_use_after_return=0 option is added to the ASAN_OPTIONS
  because ASAN uses a "shadow stack" to track stack variable lifetimes
  and this confuses Postgres' stack depth check [2].

- Perl is updated to the newer version (perl5.40-i386-linux-gnu).

- LLVM-14 is no longer default installation, no need to force using
  LLVM-16.

- Switch MinGW CC/CXX to x86_64-w64-mingw32ucrt-* to fix build failure
  from missing _iswctype_l in mingw-w64 v12 headers.
