Implement Make `handle_alloc_error` default to panic (for no_std + liballoc)
Related: https://github.com/rust-lang/rust/issues/66741 Guarded with `#![feature(default_alloc_error_handler)]` a default `alloc_error_handler` is called, if a custom allocator is used and no other custom `#[alloc_error_handler]` is defined. The panic message does not contain the size anymore, because it would pull in the fmt machinery, which would blow up the code size significantly.
