fix resize for fp16 (#19110)

resize for fp16 has 2 issues: scales are always f32 and roi can be f32
or f16.
scales:
this is fixed.

roi
this is fixed for the case where roi is not passed as optional input
with f16. To fix this it requires a much larger change and I did not
want to risk this short before a release. For all practical purpose
passing roi as input with f16 should be rare and we can fix it in the
near future.
