gh-118335: Configure Tier 2 interpreter at build time (#118339) 
The code for Tier 2 is now only compiled when configured
with `--enable-experimental-jit[=yes|interpreter]`.

We drop support for `PYTHON_UOPS` and -`Xuops`,
but you can disable the interpreter or JIT
at runtime by setting `PYTHON_JIT=0`.
You can also build it without enabling it by default
using `--enable-experimental-jit=yes-off`;
enable with `PYTHON_JIT=1`.

On Windows, the `build.bat` script supports
`--experimental-jit`, `--experimental-jit-off`,
`--experimental-interpreter`.

In the C code, `_Py_JIT` is defined as before
when the JIT is enabled; the new variable
`_Py_TIER2` is defined when the JIT *or* the
interpreter is enabled. It is actually a bitmask:
1: JIT; 2: default-off; 4: interpreter.

gh-58032: Do not use argparse.FileType in module CLIs and scripts (GH-113649) 
Open and close files manually. It prevents from leaking files,
preliminary creation of output files, and accidental closing of stdin
and stdout.

gh-102676: Add more convenience properties to `dis.Instruction` (#103969) 
Adds start_offset, cache_offset, end_offset, baseopcode,
baseopname, jump_target and oparg to dis.Instruction.

Also slightly improves the disassembly output by allowing
opnames to overflow into the space reserved for opargs.

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.
