Never used, but try it out.  It seems it's already a built-in cache
of whatever the buffer's truename is (and the docstring says
it does call the slow `file-truename`).  But like in my patch, it's
a one-time thing.  So yeah, if it's available in old Emacsen as well,
 it could replace `eglot--cached-tdi`, but then the search in the
publishDiagnostics
handler would have to be adjusted accordingly to call uri-to-path again.

Try it out, may be cleaner indeed.

Beware though, Stefan has fixed the tests which is very good, but there
still isn't a test for the symlink scenario, so you'd have to test it
manually (or
even better, craft that test yourself, with clangd).
