feat: add Trino parser to monorepo (#27)

Add ANTLR4-based Trino SQL parser (formerly PrestoSQL) from trino-parser repository into the parser monorepo.

Changes:
- Add trino/ directory with grammar files (TrinoLexer.g4, TrinoParser.g4)
- Add Makefile with build and test targets following the pattern of other parsers
- Include 94 SQL test examples covering comprehensive Trino SQL features
- Update package name and import paths to github.com/bytebase/parser/trino
- Add trino to CI workflow to run tests automatically
- All 94 test cases passing

Test coverage includes:
- DDL statements (CREATE, ALTER, DROP for tables, views, schemas, roles, materialized views)
- DML statements (SELECT, INSERT, UPDATE, DELETE, MERGE)
- Query features (CTEs, window functions, aggregations, joins, subqueries)
- Transaction control (START TRANSACTION, COMMIT, ROLLBACK)
- Session management (SET SESSION, RESET SESSION, SET ROLE)
- Security (GRANT, REVOKE, DENY)
- Administrative commands (SHOW, DESCRIBE, ANALYZE, EXPLAIN)
- Trino-specific features (table functions, refresh materialized view, etc.)

+# Trino grammar for ANTLR4
+
+An ANTLR4 grammar for Trino, formerly known as PrestoSQL.
+This grammar is based on the actively maintained [Trino repository](https://github.com/trinodb/trino).
+
+The lexer and parser are referenced from the [offical base antlr file](https://github.com/trinodb/trino/blob/master/core/trino-parser/src/main/antlr4/io/trino/sql/parser/SqlBase.g4).
+Changes are made to accommodate various language targets as the official one is being developed for Java only.
+
+The examples are extracted from the [offical test file](https://github.com/trinodb/trino/blob/master/core/trino-parser/src/test/java/io/trino/sql/parser/TestSqlParser.java).
