Scott Graham 9a97daff39 Add libfuzzer support
Adds the build support for using libfuzzer controlled by setting
`crashpad_use_libfuzzer=true`.

Also adds a first fuzzer (for ElfImageReader). Currently only runs on
Linux, but should work on Fuchsia too with some minor fixes (not sure
yet whether the fixes required are toolchain or in our build setup).

Run as:
  out/lin/elf_image_reader_fuzzer snapshot/elf/elf_image_reader_fuzzer_corpus/
hits an OOM pretty quickly in trying to allocate a giant buffer.

Bug: crashpad:30, crashpad:196, crashpad:233
