SQLite: Support multi-word type names

[LucaCappelletti94]

This PR lets SQLiteDialect parse type names made of several words or string literals in column definitions, CAST and ALTER TABLE ... ADD. Column constraints such as NOT NULL, PRIMARY KEY or DEFAULT still end the type name.

CREATE TABLE t (a UNSIGNED BIG INT, b NATIVE CHARACTER(70), c 'text');
SELECT CAST(a AS foo bar) FROM t;
-- Previously: Expected: ',' or ')' after column definition, found: BIG

SQLite accepts any sequence of names as a type, see datatypes.
