This PR extends MSSQL CREATE FUNCTION support to cover the full spectrum of function types: inline table-valued functions (which use RETURNS TABLE with AS RETURN followed by a SELECT), multi-statement table-valued functions (which declare a named table variable like @result TABLE(...) and populate it inside a BEGIN...END block), and makes the AS keyword optional before the function body. It also allows column constraints in table return type definitions and supports bare SELECT statements (without parentheses) after RETURN.",

The fix separates \"nested delimited identifiers\" into their own concept in the dialect trait, with a dedicated peek-ahead method that determines whether brackets represent identifiers or array/JSON access, and updates the tokenizer to handle nested quoting (outer brackets with optional inner double-quotes) as a distinct tokenization path.",

MSSQL (Azure SQL Data Warehouse) uses richer `WITH` clause syntax including `CLUSTERED INDEX`, `CLUSTERED COLUMNSTORE INDEX`, `HEAP`, and `PARTITION` options that don't follow the key-value pattern. This change extends the SQL option representation and parsing to support these MSSQL-specific table creation options.",

This means SQL statements like `CREATE TABLE t (i INTERVAL YEAR TO MONTH)` or casts like `'1 second'::INTERVAL HOUR TO SECOND(3)` cannot be properly parsed or round-tripped.
