- always remove FC's internal attribute everywhere before deciding whether
  a cast is needed.
- ACSL and C decisions to cast are similar
- only unroll type for checking equality. If a cast is needed, keep
  typedef (if any) as target

Removes unused declarations in plugins registration files.

Since we use only `frama-c` which is native of byte when available:
- remove: if frama-c is called add the options
- remove: add PTESTS_FILE if it is not present

Adds variables to replace without hurdles:
- @FRAMA_C_PLUGINS_OPTIONS@: -autoload-plugins -plugins ... -load-module ...
- @OPTIONS@: the OPT
- @frama-c@: frama-c @FRAMA_C_PLUGINS_OPTIONS@ @PTEST_FILE@ @OPTIONS@
