[fix](fe) Fix IS TRUE/ IS FALSE predicate null semantics (#64696)
### What problem does this PR solve?
Problem Summary: `IS TRUE`, `IS FALSE`, `IS NOT TRUE`, and `IS NOT
FALSE` in Nereids did not preserve SQL three-valued logic correctly
because the parser reused generic boolean expressions instead of
representing these predicates explicitly. This patch adds Nereids
`IsTrue` and `IsFalse` expressions, parses `IS TRUE` and `IS FALSE` into
those nodes, and rewrites them during expression analysis to boolean
casts guarded by `IS NOT NULL`. With the existing `NOT` wrapper from
parsing, `IS NOT TRUE` and `IS NOT FALSE` now correctly include NULL
rows.
### Release note
Fix Nereids null semantics for `IS TRUE`, `IS FALSE`, `IS NOT TRUE`, and
`IS NOT FALSE` predicates.
