[llvm] Win release packaging: Don't try to use rpmalloc for 32-bit x86 (PR #106969)

[via llvm-commits]

https://github.com/zmodem created https://github.com/llvm/llvm-project/pull/106969

because that doesn't work (results in `LINK : error LNK2001: unresolved external symbol malloc`).
Based on the title of #91862 it was only intended for use in 64-bit builds.
