Tom Eccles c734d77b99 [flang][semantics][OpenMP] no privatisation of stmt functions (#106550) ...

OpenMP prohibits privatisation of variables that appear in expressions
for statement functions.

This is a re-working of an old patch https://reviews.llvm.org/D93213 by
@praveen-g-ctt.

The old patch couldn't be landed because of ordering concerns. Statement
functions are rewritten during parse tree rewriting, but this was done
after resolve-directives and so some array expressions were incorrectly
identified as statement functions. For this reason **I have opted to
re-order the semantics driver so that resolve-directives is run after
parse tree rewriting**.

Closes #54677
