A series of improvements have been made for reflection of CHECK constraints on SQLite. The reflection logic now correctly handles table names containing the strings "CHECK" or "CONSTRAINT", properly supports all four SQLite identifier quoting styles (double quotes, single quotes, brackets, and backticks) for constraint names, and accurately parses CHECK constraint expressions containing parentheses within string literals using balanced parenthesis matching with string context tracking. Big thanks to GruzdevAV for new test cases and implementation ideas. Fixes: #12924 Change-Id: I0390ac334c98e934c7e0353f47c9f43204791af5
