fix(terminal): only refresh process specifics for given PID in get_cwd() (#3472)

Browse source 
Update `get_cwd()` to only refresh process specifics for the given PID,
matching the `get_cwds()` implementation.

This significantly reduces the latency of opening a new Pane or Tab.

On a 64-core Threadripper system, this reduces the latency of
`get_cwd()` from 850ms to 1ms. On an 8-core Ryzen system, the
improvement is smaller, but still perceptible.
