Make hints aware of the current directory (#10780)

Browse Source 
This commit uses the new `CwdAwareHinter` in reedline. Closes #8883.

# Description

Currently, the history based hints show results from all directories,
while most commands make sense only in the directory they were run in.
This PR makes hints take the current directory into account.

# User-Facing Changes

Described above.

I haven't yet added a config option for this, because I personally
believe folks won't be against it once they try it out. We can add it if
people complain, there's some time before the next release.

Fish has this without a config option too.

# Tests + Formatting

If tests are needed, I'll need help as I'm not well versed with the
codebase.
