Details of the allocation that caused a `TryReserveError`

## Variants

`CapacityOverflow`
🔬 This is a nightly-only experimental API. (`try_reserve_kind` #48043)

Uncertain how much info should be exposed

Error due to the computed capacity exceeding the collection’s maximum (usually `isize::MAX` bytes).

`AllocError`
🔬 This is a nightly-only experimental API. (`try_reserve_kind` #48043)

Uncertain how much info should be exposed

The memory allocator returned an error

### Fields of AllocError

`layout: Layout`
🔬 This is a nightly-only experimental API. (`try_reserve_kind` #48043)

Uncertain how much info should be exposed

The layout of allocation request that failed
