“LIKE”, "CONTAINS", "REGEX_LIKE" operators ignore collations

The query LIKE operator and family just translates into a SQL LIKE operator, etc, and SQLite's implementation of it ignores collations: it's always case-insensitive for ASCII but case-sensitive and diacritic-sensitive for non-ASCII (it just compares non-ASCII bytes bit-for-bit.)

We will need to implement our own function that's aware of the collation applied to the LHS.
