[SQL][MINOR] Make use of TypeCoercion.findTightestCommonType while
inferring CSV schema.
## What changes were proposed in this pull request?
Current the CSV's infer schema code inlines
`TypeCoercion.findTightestCommonType`. This is a minor refactor to make use of
the common type coercion code when applicable. This way we can take advantage
of any improvement to the base method.
Thanks to @MaxGekk for finding this while reviewing another PR.
## How was this patch tested?
This is a minor refactor. Existing tests are used to verify the change.
