Rollup merge of #77439 - varkor:min_const_generics-tests, r=lcnr,estebank 
Fix missing diagnostic span for `impl Trait` with const generics, and add various tests for `min_const_generics` and `const_generics`

Closes https://github.com/rust-lang/rust/issues/61410.

Adds `min_const_generics` tests for:
- https://github.com/rust-lang/rust/issues/73727
- https://github.com/rust-lang/rust/issues/72293
- https://github.com/rust-lang/rust/issues/67375
- https://github.com/rust-lang/rust/issues/75153
- https://github.com/rust-lang/rust/issues/71922
- https://github.com/rust-lang/rust/issues/69913
- https://github.com/rust-lang/rust/issues/67945
- https://github.com/rust-lang/rust/issues/69239

Adds `const_generics` tests for:
- https://github.com/rust-lang/rust/issues/67375
- https://github.com/rust-lang/rust/issues/75153
- https://github.com/rust-lang/rust/issues/71922
- https://github.com/rust-lang/rust/issues/69913
- https://github.com/rust-lang/rust/issues/67945
- https://github.com/rust-lang/rust/issues/69239

(I only added separate `min_const_generics` and `const_generics` tests if they were handled differently by the two features.)

We need to figure out how to deduplicate when `const_generics` is stabilised, but we can discuss that later. For now, we should be checking neither feature breaks, so require regression tests for both. I've given them identical names when I've added both, which should make it easier to spot them later.

cadd12b5f0 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.

Rollup merge of #76851 - fusion-engineering-forks:fixme-nonzero, r=petrochenkov 
Fix 'FIXME' about using NonZeroU32 instead of u32.

It was blocked by #58732 (const fn NonZeroU32::new), which is fixed now.

1aaafac6ff Add support for cmse_nonsecure_entry attribute 
This patch adds support for the LLVM cmse_nonsecure_entry attribute.
This is a target-dependent attribute that only has sense for the
thumbv8m Rust targets.
You can find more information about this attribute here:

3cbd17fcc6 Remove rustc_allow_const_fn_ptr 
This was a hack to work around the lack of an escape hatch for the "min
`const fn`" checks in const-stable functions. Now that we have co-opted
`allow_internal_unstable` for this purpose, we no longer need the
bespoke attribute.
