  [flang] Delete the legacy array-value operations from FIR (#213159)

Nothing in flang has produced fir.array_load, fir.array_fetch,
fir.array_update, fir.array_modify, fir.array_access, fir.array_amend,
or fir.array_merge_store since the legacy (non-HLFIR) expression
lowering was deleted (#210385, #210621, #210639, #210873), and the
array-value-copy pass that legalized them is gone (#211816, #212643).
Delete the operations and the surface that existed only for them:

- FIROps.td: the "Array value operations" section including the
copy-in/copy-out design comment; FIROps.cpp: the ops verifiers, effects
and getExtents. fir.array_coor is unrelated and stays, as does the
validTypeParams helper shared with fir.pack_array.
- Tests: the ops roundtrip/verifier blocks in fir-ops.fir and
invalid.fir; scaffolding rewrites in inline-elemental.fir (store via
hlfir.designate; hlfir.apply-in-do_loop coverage preserved),
loop-versioning.fir @test4 (the versioned loops are untouched), and
simplifyintrinsics.fir (inert copy-back loops dropped; no CHECK lines
affected).
- Docs: FIRArrayOperations.md (+ the index.md toctree line); past-tense
updates in HighLevelFIR.md; a stale comment in MutableBox.h; a
release-note entry recording the removal for downstream projects.
FIRLangRef is generated from FIROps.td and follows automatically.
