  Log Message:
  -----------
  [flang] Delete the unused ragged-array runtime builders (#213160)

The ragged-array machinery served the legacy FORALL mask temporaries,
whose lowering was removed with the legacy expression lowering (#210639,
#210873) and the array-value-copy pass (#212643). The builders
(fir::runtime::genRaggedArrayAllocate/Deallocate) and the
getRaggedArrayHeaderType helper have no compiler callers left; only
their own unit test exercised them. Delete the builders, the helper, and
the unit test.

The flang-rt runtime entry points
(RaggedArrayAllocate/RaggedArrayDeallocate in
flang-rt/lib/runtime/ragged.cpp and their declarations in
flang/include/flang/Runtime/ragged.h) are ABI and remain.
