    Eglot: unbreak eglot-extend-to-xref on w32
    
    Because of a drive-letter casing mismatch between 'buffer-file-name'
    and the return value of 'url-generic-parse-url', the hash-table test
    'equal' in 'eglot-current-server' failed.
    
    This failed to recognize that the file xref landed us on really is
    managed by the language server that facilitated that jump.
    
    The function w32-long-file-name seems to convert "C:/Users/" to
    "c:/Users" consistently and so is a good addition to
    eglot--uri-to-path.
    
    * lisp/progmodes/eglot.el (eglot--uri-to-path): Use
    w32-long-file-name.
