  [flang][stack-arrays] Extend pass to work on declare ops and within omp regions (#98810)

Extends the stack-arrays pass to support `fir.declare` ops. Before that,
we did not recognize malloc-free pairs for which `fir.declare` is used
to declare the allocated entity. This is because the `free` op was
invoked on the result of the `fir.declare` op and did not directly use
the allocated memory SSA value.

This also extends the pass to collect the analysis results within OpenMP
regions.
