  [flang][acc] Allow orphaned acc cache directive (#184448)

While the spec allows the cache directive at the top of a loop body, the
directive has also been utilized at the top of an acc routine. This PR
removes the semantic check that rejects the cache directive outside of a
loop, allowing orphaned `!$acc cache` similar to CIR.

The OpenACC.md deviation document is updated to note this extension.
