Introduce Py_TPFLAGS_IMMUTABLETYPE flag for immutable type objects, and
modify PyType_Ready() to set it for static types.

Add new C-API functions to control the state of the garbage collector:
PyGC_Enable(), PyGC_Disable(), PyGC_IsEnabled(),
corresponding to the functions in the gc module.

Removes the `list` call in the Popen `repr`.
Current implementation:
For cmd = `python --version`, with `shell=True`.
```bash
<Popen: returncode: None args: ['p', 'y', 't', 'h', 'o', 'n', ' ', '-', '-',...>
```
For `shell=False` and args=`['python', '--version']`, the output is correct:
```bash
<Popen: returncode: None args: ['python', '--version']>
```
With the new changes the `repr` yields:
For cmd = `python --version`, with `shell=True`:
```bash
<Popen: returncode: None args: 'python --version'>
```
For `shell=False` and args=`['python', '--version']`, the output:
```bash
<Popen: returncode: None args: ['python', '--version']>
```

Faster bz2/lzma/zlib via new output buffering.
Also adds .readall() function to _compression.DecompressReader class
to take best advantage of this in the consume-all-output at once scenario.
Often a 5-20% speedup in common scenarios due to less data copying.

* Add signal_state_t structure and signal_global_state variable.
* Add a module state to the _signal module.
* Move and rename variables:
* DefaultHandler becomes state->default_handler
* IgnoreHandler becomes state->ignore_handler
* sigint_event becomes state->sigint_event
* ItimerError becomes modstate->itimer_error
* Rename SetHandler() to set_handler() to be consistent with
get_handler().
Importing the _signal module in a subinterpreter has no longer side
effects.
signal_module_exec() no longer modifies Handlers and no longer attempts
to set SIGINT signal handler in subinterpreters.
In 3.12 ``True`` or ``False`` will be returned for all containment checks,
with ``True`` being returned if the value is either a member of that enum
or one of its members' value.
In 3.12 the enum member, not the member's value, will be used for
format() calls. Format specifiers can be used to retain the current
display of enum members:
Example enumeration:
class Color(IntEnum):
RED = 1
GREEN = 2
BLUE = 3
Current behavior:
f'{Color.RED}' --> '1'
Future behavior:
f'{Color.RED}' --> 'RED'
Using d specifier:
f'{Color.RED:d}' --> '1'
Using specifiers can be done now and is future-compatible.
The check about the f argument type was removed in this commit:
