Rollup merge of #127483 - BertalanD:no_sanitize-global-var, r=rcvalle

Allow disabling ASan instrumentation for globals

AddressSanitizer adds instrumentation to global variables unless the [`no_sanitize_address`](https://llvm.org/docs/LangRef.html#global-attributes) attribute is set on them.

This commit extends the existing `#[no_sanitize(address)]` attribute to set this; previously it only had the desired effect on functions.
