Rollup merge of #126953 - joboet:lazy_key, r=jhpratt
std: separate TLS key creation from TLS access Currently, `std` performs an atomic load to get the OS key on every access to `StaticKey` even when the key is already known. This PR thus replaces `StaticKey` with the platform-specific `get` and `set` function and a new `LazyKey` type that acts as a `LazyLock<Key>`, allowing the reuse of the retreived key for multiple accesses. Related to #110897.
