[flang] Correctly handle `!dir$ unroll` with unrolling factors of 0 and 1 (#126170)
https://github.com/llvm/llvm-project/pull/123331 added support for the
unrolling directive. In the presence of an explicit unrolling factor,
that unrolling factor would be unconditionally passed into the metadata
even when it was 1 or 0. These special cases should instead disable
unrolling. Adding an explicit unrolling factor of 0 triggered this
assertion which is fixed by this patch:
```
unsigned int unrollCountPragmaValue(const llvm::Loop*):
Assertion `Count >= 1 && "Unroll count must be positive."' failed.
```
Updated tests and documentation.
