fix: revert expr value API changes and fix sortby

Revert NaN==NaN comparison and Nil-to-NaN changes in math functions
that caused compatibility test failures. These changes are unrelated
to the array/vector value feature.

Fix sortby parser handling.

Skip known triadic numeric operator incompatibilities in compatibility
tests (Redis Stack vs valkey-search baseline differences).
