[libpas] Enable MTE in libpas-only builds

Summary [libpas] Enable MTE in libpas-only builds
Marcus Plutowski
Reported 2026-01-08 14:10:49 PST
Currently, the PAS_ENABLE_MTE guard macro is only set when PAS_BMALLOC is defined — i.e. when libpas is being built as part of a bmalloc build. This means that freestanding builds of libpas cannot leverage MTE — including the test suite. This should be changed so that we can move forward with our plans to more thoroughly test MTE tagging policies & behavior as part of libpas’ own test suite. Doing so will at least require filling in for the g_config storage normally provided by WTF.
