feat(wm): add cmd to id layered apps

Users on Discord noted that Microsoft Office applications were not being
handled correctly by the wm. After some investigation it was clear that
this was because the application windows had WS_EX_LAYERED set.

This had only been seen once before with Steam, and so a whitelist for
layered applications was previously added to the codebase with steam.exe
hard-coded, but this had not been exposed via the cli.

This commit adds a command to allow users to specify layered
applications which should be managed, and also renames the whitelist to
reflect that classes can also be used to identify applications on the
whitelist.

A section has been added to the README to guide Microsoft Office users
to guide Microsoft Office users in configuring komorebi to correctly
handle Office applications with Word given as an example.

This commit also renames the identify-border-overflow command to
identify-border-overflow-application for consistency, while retaining
the previous command as an alias to maintain compatibility with existing
user configurations.

It should be noted however, that those like me who are using the
generated komorebic AHK library, will have to update any AHK function
calls to use IdentifyBorderOverflowApplication().
