opt_dff: fix sequence point copy paste bug
...
Newer GCCs emit the following warning for opt_dff:
passes/opt/opt_dff.cc:560:17: warning: operation on ‘ff.Yosys::FfData::has_clk’ may be undefined [-Wsequence-point]
560 | ff.has_clk = ff.has_ce = ff.has_clk = false;
| ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Which is correct: the order of whether the read or write of has_clk
occurs first is undefined since there is no sequence point between them.
This is almost certainly just a typo/copy paste error and objectively
wrong, so just fix it.

FfData: some refactoring.
...
- FfData now keeps track of the module and underlying cell, if any (so
calling emit on FfData created from a cell will replace the existing cell)
- FfData implementation is split off to its own .cc file for faster
compilation
- the "flip FF data sense by inserting inverters in front and after"
functionality that zinit uses is moved onto FfData class and beefed up
to have dffsr support, to support more use cases
