Rename caffeinate.run to .call and match the subprocess.call API.

I'm looking at caffeinating more long-running depot_tools commands on
Mac, which use a variety of `subprocess` APIs; one implementation
strategy I'm considering is to wrap more of them, including
`subprocess.run`, but the most obvious name to wrap `subprocess.run`
into is already taken! I think it makes the most sense to name the
`caffeinate` function(s) after the `subprocess` call it wraps.

The callers to other parts of `subprocess` use more of the features
exposed by those APIs. For consistency, I am plumbing through more of
`subprocess.call`'s identifiable behaviors here, too:

* command-to-invoke parameter is named "args"
* as explicitly checked in cpython's subprocess.py's `_posix_spawn`:
  77cb39e0c7/Lib/subprocess.py (L1816)
  also allow `str`, `bytes`, and `os.PathLike` for the type of `args`,
  converting the non-list-like types into a single-element list
* use kwargs packing and unpacking to forward other parameters into
  `subprocess.call`

kwargs packing does not provide perfect emulation as implemented:
77cb39e0c7/Lib/subprocess.py (L386)
`timeout` could be provided as a positional parameter. However, Python
documents all subprocess.call parameters as keyword only:
https://docs.python.org/3.12/library/subprocess.html#older-high-level-api
...specifically because they don't want to bother distinguishing
between parameters "local" to a higher-level `subprocess` helper and
those that get forwarded (via `**kwargs`) to the underlying `Popen`,
so I think it is reasonable to follow their lead on that.
