[roll third_party/pigweed] pw_chre: Add barebones CHRE
NOTE: This is a very work-in-progress implementation.
Add GN rules for the CHRE codebase into //third_party/CHRE.
This also adds a pw_chre_PLATFORM_BACKEND gn argument for the
platform backend for CHRE.
Add a pw_chre directory that includes all of the class and
function definitions required to compile CHRE. Some of this
connects to pigweed functionality, some of it is stubbed out.
//pw_chre:chre_simulator uses pw_system to run CHRE on
pigweed on the host, and it compiles in a number of CHRE's
example nanoapps. There is enough functionality that these
nanoapps are able to run.
