rts: introduce (and use) `STG_NORETURN`

Instead of sprinkling the codebase with
`GNU(C3)_ATTRIBUTE(__noreturn__)`, add a `STG_NORETURN` macro (for,
basically, the same thing) similar to `STG_UNUSED` and others, and
update the code to use this macro where applicable.

rts: introduce (and use) `STG_MALLOC`

Instead of using `GNUC3_ATTRIBUTE(__malloc__)`, provide a `STG_MALLOC`
macro definition and use it instead.

rts: specify deallocator of allocating functions

This patch adds a new `STG_MALLOC1` macro (and its counterpart
`STG_MALLOC2` for completeness) which allows to specify the deallocation
function to be used with allocations of allocating functions, and
applies it to `stg*allocBytes`.

It also fixes a case where `free` was used to free up an
`stgMallocBytes` allocation, found by the above change.

rts: use `alloc_size` attribute

This patch adds the `STG_ALLOC_SIZE1` and `STG_ALLOC_SIZE2` macros which
allow to set the `alloc_size` attribute on functions, when available.

gen-dll: Drop it

Currently it is only used by the make build system, which is soon to be
retired, and it has not built since 41cf758b. We may need to reintroduce
it when dynamic-linking support is introduced on Windows, but we will
cross that bridge once we get there.

Fixes #21753.

Port foundation numeric tests to GHC testsuite

This commit ports the numeric tests which found a regression in GHC-9.4.

https://github.com/haskell-foundation/foundation/issues/571

Included in the commit is a simple random number generator and
simplified QuickCheck implementation. In future these could be factored
out of this standalone file and reused as a general purpose library
which could be used for other QuickCheck style tests in the testsuite.

See #22282

Clarify status of bindings in WholeCoreBindings

Gergo points out that these bindings are tidied, rather than prepd as
the variable claims. Therefore we update the name of the variable to
reflect reality and add a comment to the data type to try to erase any
future confusion.

Fixes #22307
