Changed the default value of the disableBytesTypePromotions setting from false to true. It has been over two years since PEP 688 was accepted, so it's time for us to stop treating bytes as an alias for bytes | bytearray | memoryview. This is a breaking change and may require an update to the pyright configuration for some code bases. This addresses #8834 . ( #8835 )

...
* Added some code improvements from a working branch:
* Created a shortened "fileId" for each source file. This reduces memory used for tracking symbols and TypeVars that are scoped to files.
* Removed some unused or redundant code.
* Added assertNever calls to catch potential bugs.
* Renamed a few symbols for consistency and readability.
* Improved handling of literal type expressions that are lazily parsed.
* Refactored literal type printing into a utility module.
* Fixed style issue.

Changed behavior for protocols that have methods with method-scoped type variables. These are no longer treated as free type variables during protocol matching, so they can be used to support rank-2 polymorphism. This behavior is not currently dictated by the typing spec, but it is more consistent with mypy. This addresses #8685 . ( #8751 )
