Merge #10067 
10067: Downmap tokens to all token descendants instead of just the first r=Veykril a=Veykril

With this we can now resolve usages of identifiers inside (proc-)macros even if they are used for different purposes multiple times inside the expansion.
Example here being with the cursor being on the `no_send_sync_value` function causing us to still highlight the identifier in the attribute invocation correctly as we now resolve its usages in there. Prior we only saw the first usage of the identifier which is for a definition only, as such we bailed and didn't highlight it.

Note that this has to be explicitly switched over for most IDE features now as pretty much everything expects a single node/token as a result from descending.
