chore: migrate 15 scalar operators to SQLGlot (#1925)
This change contains three commits generated by Gemini CLI tool: Migrated cosh_op, tanh_op, arcsinh_op, arccosh_op, and arctanh_op scalar operators to SQLGlot. Migrated abs_op, capitalize_op, ceil_op, date_op, and day_op scalar operators to SQLGlot. Migrated dayofweek_op, dayofyear_op, exp_op, expm1_op, and floor_op scalar operators to SQLGlot. Fixes internal issue 430133370
