`provide_sorted_batch` in core is incorrectly marked with `#[cfg(not(no_global_oom_handling))]` which prevents core from building with the cfg enabled. Nothing in core allocates memory including this function, so the `cfg` gate is incorrect.

With the current Rust nightly (2023-06-01 as of this writing), using `-Zbuild-std` to recompile the `core` and `alloc` crates while enabling the `no_global_oom_handling` cfg now works properly. Therefore there is no further need for the `doors_alloc` hack, which involved manually copying the source for `alloc` and adding it as a Cargo dependency. It is still not clear what change on the Rust/Cargo end fixed the bug that previously blocked using `-Zbuild-std` to set the cfg (at the time, trying to enable the cfg resulted in large numbers of mysterious "duplicate lang item" errors). Maybe rust-lang/rust#110649 is related.
