Extends #95Closes#82
Adds parsing of new `type` soft keyword for defining type aliases.
Supports type alias statements as defined in PEP 695 e.g.
```python
type IntOrStr = int | str
type ListOrSet[T] = list[T] | set[T]
type AnimalOrVegetable = Animal | "Vegetable"
type RecursiveList[T] = T | list[RecursiveList[T]]
```
All type parameter kinds are supported as in #95.
Builds on soft keyword abstractions introduced in https://github.com/RustPython/RustPython/pull/4519
## Summary
This PR adds `TextRange` to `Identifier`. Right now, the AST only
includes ranges for identifiers in certain cases (`Expr::Name`,
`Keyword`, etc.), namely when the identifier comprises an entire AST
node. In Ruff, we do additional ad-hoc lexing to extract identifiers
from source code.
One frequent example: given a function `def f(): ...`, we lex to find
the range of `f`, for use in diagnostics.
Another: `except ValueError as e`, for which the AST doesn't include a
range for `e`.
Note that, as an optimization, we avoid storing the `TextRange` for
`Expr::Name`, since it's already included.
* Move `range` from `Attributed` to `Node`s
* No Attributed + custom for Range PoC
* Generate all located variants, generate enum implementations
* Implement `Copy` on simple enums
* Move `Suite` to `ranged` and `located`
* Update tests

- Split parser core and compiler core. Fix#14
- AST int type to `u32`
- Updated asdl_rs.py and update_asdl.sh fix#6
- Use `ruff_python_ast::SourceLocation` for Python source location. Deleted our own Location.
- Renamed ast::Located to ast::Attributed to distinguish terms for TextSize and SourceLocation
- `ast::<Node>`s for TextSize located ast. `ast::located::<Node>` for Python source located ast.
- And also strictly renaming `located` to refer only python location related interfaces.
- `SourceLocator` to convert locations.
- New `source-code` features of to disable python locations when unnecessary.
- Also including fully merging https://github.com/astral-sh/RustPython/pull/4closes#9
