hadrian: Build all executables in bin/ folder

In the end the bindist creation logic copies them all into the bin
folder. There is no benefit to building a specific few binaries in the
lib/bin folder anymore.

This also removes the ad-hoc logic to copy the touchy and unlit
executables from stage0 into stage1. It takes <1s to build so we might
as well just build it.

testsuite: mark jspace as fragile on i386.

This test has been flaky for some time and has been failing consistently on
i386-linux since 8e0446df landed.

See #24261

Deprecate -ddump-json and introduce -fdiagnostics-as-json

Addresses #19278

This commit deprecates the underspecified -ddump-json flag and
introduces a newer, well-specified flag -fdiagnostics-as-json.

Also included is a JSON schema as part of the documentation.

The -ddump-json flag will be slated for removal shortly after this merge.

genSym: Reimplement via CAS on 32-bit platforms

Previously the remaining use of the C implementation on 32-bit platforms
resulted in a subtle bug, #24261. This was due to the C object (which
used the RTS's `atomic_inc64` macro) being compiled without `-threaded`
yet later being used in a threaded compiler.

Side-step this issue by using the pure Haskell `genSym` implementation on
all platforms. This required implementing `fetchAddWord64Addr#` in terms
of CAS on 64-bit platforms.

This reverts commit 0038d052c8c80b4b430bb2aa1c66d5280be1aa95.

Refactor: store [[PrimRep]] rather than [Type] in STG

StgConApp stored a list of types. This list was used exclusively
during unarisation of unboxed sums (mkUbxSum).
However, this is at a wrong level of abstraction:
STG shouldn't be concerned with Haskell types, only PrimReps.
Update the code to store a [[PrimRep]]. Also, there's no point in storing
this list when we're not dealing with an unboxed sum.

EPA: Tackling extra parser allocations stats fail

- make all getCommentsFor results strict.
- adding `seq` to various Parser.y helper functions

This metric increases 2.6% (6% before the mitigations in this commit)
I think the balance are inherent to the change in GhcPs structure, it
is a pathological case with HsAppTy repeating thousands of times.

Metric Increase:
    parsing001
