Subject: [PATCH] perf(str): `static_ident!` and `static_str!` macros guarantee
 const evaluation (#28340)

`static_ident!` and `static_str!` macros are intended to evaluate at compile time. This is especially valuable for `static_ident!` as we want the hash to be calculated at compile time.

Wrap both in a `const { ... }` block to ensure they are const-evaluated.
