Moves and renames the existing pw::string::Length to
pw::string::internal::ClampedLength. Instead two new helpers are added:
1) pw::string::NullTerminatedLength(...) which returns the length IFF
the string is null terminated.
2) pw::string::ClampedCString(...) which returns a string_view of
the clamped string. This is considered safer compared to strnlen_s
and the existing internal::ClampedLength implementation, since
sting_view does not require null termination.

Adds a "//targets/host:host_clang_fuzz" target so fuzzers get built
along with other build targets. This new target uses "address" as the
default sanitizer for fuzzing. Sanitizers are overridable via
pw_toolchain_SANITIZERS.
Adds a top-level "fuzzers" target so it could be used (e.g. by
OSS-Fuzz) to just fuzzers.
Test: build normally and run
`//out/host_clang_fuzz/obj/pw_fuzzer/bin/toy_fuzzer`

The fuzzer hasn't worked for a bit due to the build refactor. This is a
CL to bring it back. Some design discussion may be needed around how
the toolchains are selected.

This CL adds fuzzing support, in the form of GN logic, docs, and an
example fuzzer.
You can run this fuzzer with the following:
$ pw_fuzzer/examples/build_and_run_toy_fuzzer.sh
This is rather bare-bones at the moment. Additional features, like
corpus and dictionary integration, more sanitizers, etc. are follow-on
work.
