Follow PEP 0394 and use /usr/bin/env python so that the python in the
users venv is respected. Not that the kitty python files are meant to be
executed standalone anyway, but, whatever.
Fixes#6810
Now a stack of depth 1 is used to save/restore private mode values. And
saving/restoring individual modes is supported. This latter is used by
midnight commander.
A better solution from an ecosystem perspective is to just work with the
original protocol. I have modified kitty's escape parser to special case
OSC 52 handling without changing its max escape code size.
Basically, it works by splitting up OSC 52 escape codes longer than the
max size into a series of partial OSC 52 escape codes. These get
dispatched to the UI layer where it accumulates them upto the 8MB limit
and then sends to clipboard when the partial sequence ends.

Up to now this poorly designed and completely unnecessary escape code
was relegated to only GNOME, however, off late Apple has started using
it as well, so silently ignore it, instead of spamming error messages
for it.
Using
```Python
with suppress(OSError):
os.remove('somefile.tmp')
```
instead of
```Python
try:
os.remove('somefile.tmp')
except OSError:
pass
```
makes the code more compact and more readable IMO.
This pattern was recommended by Raymond Hettinger, a Python Core
Developer in his talk "Transforming Code into Beautiful, Idiomatic Python" at https://www.youtube.com/watch?v=OSGv2VnC0go. The transcript is available at https://github.com/JeffPaine/beautiful_idiomatic_python
