x86/rust: support MITIGATION_SLS
Support `MITIGATION_SLS` by enabling the target features that Clang does.
Without this, `objtool` would complain if enabled for Rust, e.g.:
rust/core.o: warning: objtool:
_R...next_up+0x44: missing int3 after ret
These should be eventually enabled via `-Ctarget-feature` when `rustc`
starts recognizing them (or via a new dedicated flag) [1].
