[roll] Roll fuchsia [superproject] Roll third_party/pigweed pw_presubmit: Add a 'host_clang_fuzz' step

This CL adds three things:

* A 'pw_strict_host_clang_fuzz' toolchain based on
  `pw_toolchain_host_clang.fuzz`.
* A top-level `//:host_clang_fuzz` GN targets which builds
  `//:pigweed_defaults` with the above toolchain.
* A `gn_fuzz_build` presubmit step which builds the above target. This
  step is added to the `SECURITY` presubmit program.

As of this CL, this new step does not do much; it merely builds and runs
existing targets such as unit tests with additional fuzzer and ASan
instrumentation. Subsequent CLs will add FuzzTest and its dependencies
to allow `pw_fuzz_test`s to run in "unit test" mode, enabling bounded
fuzzing in presubmit.
