Rollup merge of #133861 - shamb0:refactor_InterpCx_allocate_str, r=RalfJung
Add allocate_bytes and refactor allocate_str in InterpCx for raw byte… Fixes https://github.com/rust-lang/miri/issues/4025 This PR introduces a new `allocate_bytes` function in InterpCx and refactors `allocate_str` to use it internally. This change improves memory allocation handling in the interpreter by: 1. Adding `allocate_bytes`: - Direct byte slice allocation support - Handles both mutable and immutable allocations - Maintains proper memory alignment and deduplication 2. Refactoring `allocate_str`: - Now uses `allocate_bytes` internally - Adds string-specific metadata handling - Preserves existing string allocation behavior This is part 1 of the planned changes to improve timezone string handling in Miri. A follow-up PR will update Miri's timezone logic to use this new allocation mechanism. Related: https://github.com/rust-lang/miri/pull/4069
