Auto merge of #63561 - HeroicKatora:alloc-private-bytes, r=oli-obk

Make Allocation::bytes private

Fixes #62931.

Direct immutable access to the bytes is still possible but redirected through the new method `raw_bytes_with_undef_and_ptr`, similar to `get_bytes_with_undef_and_ptr` but without requiring an interpretation context and not doing *any* relocation or bounds checks. The `size` of the allocation is stored separately which makes access as `Size` and `usize` more ergonomic.
