Improve numerice_coercion and reuse in both compare op and math op

[jayzhan211]

Which issue does this PR close?

Ref #8302

Rationale for this change

1. Fix numeric coercion

• Support f16 and fix f32 coercion
  Some type coercion seems incorrect for me, and f16 is not considered.

Something like, but not only

Prev	PR
(u64, f32) -> f32	(u64, f32) -> f64
(i64, f32) -> f32	(i64, f32) -> f64

• exact_numeric_coercion
  To differentiate the current possible lossy numeric_coercion. I think it might be helpful somewhere, but keep it todo!() until we need it.

2. use common coercion for compare op and math op since I dont think we need two version for these two.

What changes are included in this PR?

Are these changes tested?

Since arrow-rs does not support f16 yet, I didn't add test for f16, just ensure the existing test does not fail.

Add math op coercion in slt. some test is not possible to move to slt yet, so keep it there.

Are there any user-facing changes?

additional context

Decimal coercion is different in compare op and math op. Not sure if we can have common coercion for them.

Thanks @jayzhan211 -- I think this PR needs some careful review to ensure it doesn't introduce subtle bugs / logic errors. I will try and find time but I worry about this PR introducing regressions for no (practical) benefit.

Could you please:

1. Add the new tests as a separate PR (to better document the current behavior)
2. Explain what, if any, issue this is solving (e.g. what queries run with this PR that did not before, or what cases work better than they did)

Thank you

If I remember correctly, we currently do not support float16, so it's challenging for us to test these scenarios.
Therefore, I do not recommend add float16 in type coercion for now.

yes, f16 is not fully support in arrow-rs, so I did not add test
