LOG: [sanitizers] Bump malloc limit to 1TB for MSAN, LSAN & DFSAN (#89728)

We already have `const uptr kMaxAllowedMallocSize = 1ULL << 40;` set for
ASAN, HWASAN, memprof, TSAN. This patch bumps the malloc limit for MSAN,
LSAN and DFSAN to 1TB as well. 8GB is simply not enough nowadays.

    compiler-rt/lib/lsan/lsan_allocator.cpp
