Make it so that PDL in pattern rewrites can be optionally disabled.
PDL is still enabled by default and not optional bazel. So this should
be a NOP for most folks, while enabling other to disable.
This only works with tests disabled. With tests enabled this still
compiles but tests fail as there is no lit config to disable tests that
depend on PDL rewrites yet.
These helpers should not be part of the IR build unit.
The interface is now implemented on `builtin.unrealized_conversion_cast` with an external model.
Also rename the CastOpInterfaces Bazel target name to CastInterfaces to be consistent with the CMake target name.

This is an ongoing series of commits that are reformatting our
Python code.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

We weren't properly returning the result of the constraint,
which leads to errors when actually trying to use the generated
C++.

This essentially sets up mlir-pdll to function in a similar manner to mlir-tblgen. Aside
from the boilerplate of configuring CMake and setting up a basic initial test, two new
options are added to mlir-pdll to mirror options provided by tblgen:
* -d
This option generates a dependency file (i.e. a set of build time dependencies) while
processing the input file.
* --write-if-changed
This option only writes to the output file if the data would have changed, which for
the build system prevents unnecesarry rebuilds if the file was touched but not actually
changed.
