Anton Bikineev 727e808fb2 cppgc: Enable 2GB cage to speed up compression/decompression
With only 2GB reservation we can make sure that the heap allocated in
such a way, that all the pointer to it have the most significant bit
in the low halfword set. This allows us to quickly distinguish between
normal pointers and nullptr/sentinel when performing sign-extension
inside decompression.
