[build][rust] Disable mutable-noalias in rust builds

It was recently discovered that mutable-noalias can lead to
miscompilations (see https://github.com/rust-lang/rust/issues/84958).
This CL disables that optimization for all rust builds.

Bug: 76184
Tests: Manually reviewed basic functionality on devices, relying on CI
for broader coverage
