utils: ipc: import mojo

Import mojo from the Chromium repository, so that we can use it for
generating code for the IPC mechanism. The commit from which this was
taken is:
a079161ec8c6907b883f9cb84fc8c4e7896cb1d0 "Add PPAPI constructs for
sending focus object to PdfAccessibilityTree"

This tree has been pruned to remove directories that didn't have any
necessary code:
- mojo/* except for mojo/public
  - mojo core, docs, and misc files
- mojo/public/* except for mojo/public/{tools,LICENSE}
  - language bindings for IPC, tests, and some mojo internals
- mojo/public/tools/{fuzzers,chrome_ipc}
- mojo/public/tools/bindings/generators
  - code generation for other languages
