#53096: fpc upgrade to 3.0.0

----------------------+-----------------
 The attached patch upgrades fpc to the current 3.0.0 release version.

 1 significant modification: the install location has been set to
 ${prefix}/libexec/fpc, to align with the principle that this is the
 location for port-specific "subprefices" (cf. the Qt and llvm ports, as
 well as MacPorts itself).
 Symlinks to the port's executables are installed in ${prefix}/bin.

 The port also contains the proposed/prototype subport for the chmcmd
 utility that is of more general interest and the subject of request #53077
 (which is thus superseded by this ticket).
