Fix various typing issues (#18187)

* Fix the `Any` typing hint treewide

There has been confusion between the Any type[1] and the any function[2]
in typing hints.

[1] https://docs.python.org/3/library/typing.html#typing.Any
[2] https://docs.python.org/3/library/functions.html#any

* Fix typing for various frame_shape members

Frame shapes are most likely defined by height and width, so a single int
cannot express that.

* Wrap gpu stats functions in Optional[]

These can return `None`, so they need to be `Type | None`, which is what
`Optional` expresses very nicely.

* Fix return type in get_latest_segment_datetime

Returns a datetime object, not an integer.

* Make the return type of FrameManager.write optional

This is necessary since the SharedMemoryFrameManager.write function can
return None.

* Fix total_seconds() return type in get_tz_modifiers

The function returns a float, not an int.

https://docs.python.org/3/library/datetime.html#datetime.timedelta.total_seconds

* Account for floating point results in to_relative_box

Because the function uses division the return types may either be int or
float.

* Resolve ruff deprecation warning

The config has been split into formatter and linter, and the global
options are deprecated.
