Dired's command makes sense: when there's no project, or we want to 
search some dirs specifically, we can fire up Dired, select the 
directories and files one by one, and do the search.

When you call xref-find-regexp, you won't get to tell exactly what you 
want. So, the command needs to have some useful, clear semantics.

xref-query-replace-in-matches will be the new name for the current 
xref-query-replace. The changed name should signify that it replaces, 
indeed, in the already-present list of matches.

Since you said that having xref-query-replace called almost the same as 
tags-query-replace is confusing.
