bpo-41746: Add type information to asdl_seq objects (GH-22223)
* Add new capability to the PEG parser to type variable assignments. For instance: ``` | a[asdl_stmt_seq*]=';'.small_stmt+ [';'] NEWLINE { a } ``` * Add new sequence types from the asdl definition (automatically generated) * Make `asdl_seq` type a generic aliasing pointer type. * Create a new `asdl_generic_seq` for the generic case using `void*`. * The old `asdl_seq_GET`/`ast_seq_SET` macros now are typed. * New `asdl_seq_GET_UNTYPED`/`ast_seq_SET_UNTYPED` macros for dealing with generic sequences. * Changes all possible `asdl_seq` types to use specific versions everywhere.
