Auto merge of #49580 - glandium:core-heap, r=SimonSapin

Use Alloc and Layout from core::heap.

94d1970bba87f2d2893f6e934e4c3f02ed50604d moved the alloc::allocator
module to core::heap, moving e.g. Alloc and Layout out of the alloc
crate. While alloc::heap reexports them, it's better to use them from
where they really come from.
