SQL: Fix issue with LIKE/RLIKE as painless script (#53495)
Add missing asScript() implementation for LIKE/RLIKE expressions. When LIKE/RLIKE are used for example in GROUP BY or are wrapped with scalar functions in a WHERE clause, the translation must produce a painless script which will be executed to implement the correct behaviour and previously this was completely missing, and as a consquence wrong results were silently (no error) returned. Fixes: #53486
