feat: support Spark-compatible abs math function part 2 - ANSI mode

[hsiang-c]

Which issue does this PR close?

• Part of [EPIC] Complete datafusion-spark Spark Compatible Functions #15914

Rationale for this change

Non-ANSI mode	ANSI mode	ANSI Interval Types
#18205	This PR	TODO

• Support ANSI mode Spark-compatible abs math function

What changes are included in this PR?

• When enable_ansi_mode is true, abs throws exception on arithmetic overflow.

Are these changes tested?

• unit tests
• SQL logic tests
  • I had to turn on with_enable_ansi_mode in test_context.rs to demonstrate how ANSI mode works. This is probably not a good idea and should revert it after review.

Are there any user-facing changes?

Yes, arithmetic overflow will be thrown when ANSI mode is on, i.e. spark.sql.ansi.enabled=true

[hsiang-c]

Turn on ANSI mode here so that sqllogictest show overflow error. We need a different way to toggle ANSI mode.

Can we just set it like so instead?

datafusion/datafusion/sqllogictest/test_files/cte.slt

Lines 45 to 47 in f1ecacc

	# Test disabling recursive CTE
	statement ok
	set datafusion.execution.enable_recursive_ctes = false;

Instead of doing it globally

@Jefffrey @comphead for review, thank you.

I can't help but feel a lot of this test code could be compacted in some way, as it seems quite verbose; haven't had time to properly check this however so don't really have a suggestion myself 🤔
