MCTargetOptionsCommandFlags.inc and CommandFlags.inc are headers which contain
cl::opt with static storage.
These headers are meant to be incuded by tools to make it easier to parametrize
codegen/mc.
However, these headers are also included in at least two libraries: lldCommon
and handle-llvm. As a result, when creating DYLIB, clang-cpp holds a reference
to the options, and lldCommon holds another reference. Linking the two in a
single executable, as zig does[0], results in a double registration.
This patch explores an other approach: the .inc files are moved to regular
files, and the registration happens on-demand through static declaration of
options in the constructor of a static object.

It's been an empty target since r360498 and friends
(`git log --grep='Move InstPrinter files to MCTargetDesc.' llvm/lib/Target`),
but due to hwo the way these targets are structured it was silently
an empty target without anyone noticing.
No behavior change.
This moves the cmake configuration for fuzzers in LLVM to a new macro,
add_llvm_fuzzer. This will make it easier to keep things consistent
while implementing llvm.org/pr34314.
I've also made a couple of minor functional changes here:
- the fuzzers now use add_llvm_executable rather than add_llvm_tool.
This means they won't create install targets and stuff like that,
because those made little sense for these fuzzers.
- I've grouped these under "Fuzzers" rather than in with "Tools" for
people who build with IDEs.

This creates an llvm-mc-disassemble-fuzzer from the existing llvm-mc-fuzzer
and finishing the assemble support in llvm-mc-assemble-fuzzer.
