pw_fuzzer: Separate fuzzers from unit tests
This CL disentangles fuzzers from unit tests. It makes the generated
unit tests an explicitly named "${target_name}_test" target, and
extracts the actual fuzzers into their own "fuzzers" groups for each
relevant module. This allows the top-level "fuzzers" group to much more
simply redirect to the `host_clang_fuzz` toolchain.
This allows `ninja -C out fuzzers` to behave as expected and only build
the fuzzers.

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
