GH-100987: Allow objects other than code objects as the "executable" of an internal frame. (GH-105727) 
* Add table describing possible executable classes for out-of-process debuggers.

* Remove shim code object creation code as it is no longer needed.

* Make lltrace a bit more robust w.r.t. non-standard frames.

gh-103763: Implement PEP 695 (#103764) 
This implements PEP 695, Type Parameter Syntax. It adds support for:

- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

GH-103082: Filter LINE events in VM, to simplify tool implementation. (GH-104387) 
When monitoring LINE events, instrument all instructions that can have a predecessor on a different line.
Then check that the a new line has been hit in the instrumentation code.
This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.

gh-87729: add LOAD_SUPER_ATTR instruction for faster super() (#103497) 
This speeds up `super()` (by around 85%, for a simple one-level
`super().meth()` microbenchmark) by avoiding allocation of a new
single-use `super()` object on each use.

Add missing variables to bytecodes.c (GH-103153)

* Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints.

* Add functions to hide some internals of long object, and for setting sign and digit count.

* Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().

gh-102654: Insert #line directives in generated_cases.c.h (#102669) 
This behavior is optional, because in some extreme cases it
may just make debugging harder. The tool defaults it to off,
but it is on in Makefile.pre.in.

Also note that this makes diffs to generated_cases.c.h noisier,
since whenever you insert or delete a line in bytecodes.c,
all subsequent #line directives will change.

* Remove unused dummy variables.
