Add project-find-file-in-root (bug#73044)

Several users have asked me for a command which is just
find-file, but starting from the project root.  In large
projects, where project-files is expensive, this will have
substantially better performance than project-find-file.

Also, it allows opening files which aren't included in
project-files without paying the further cost of running
project--files-in-directory (which is what happens when passing
INCLUDE-ALL=t to project-find-file).

Also, it may help with user confusion about why
project-find-file doesn't behave like find-file (which I've
encountered a few times).

This command is equivalent to C-x p o C-x C-f, but it's nice to
be able to bind it to a specific key.

Overall, this is easy enough to provide, so let's just do that.
