[ASan][X86] Mark asan_globals section large (#74514)

We'd like to make the asan_globals section large to make it not
contribute to relocation pressure since there are no direct PC32
references to it.

Following #74498, we can do that by marking the code model for the
global explicitly large.

Without this change, asan_globals gets placed between .data and .bss.
With this change, it gets placed after .bss.
