Update OWNERS file

This CL isolates the NNAPI owners into a unique file so that other
OWNERS files can "include" this file, making it simpler to maintain
who the current NNAPI owners are. This CL includes NNAPI_OWNERS from
packages/modules/NeuralNetworks, and a follow up CL will make the same
change for the OWNERS file in hardware/interfaces/neuralnetworks.

This change also:
* adds [email protected] as an owner
* adds [email protected] as an owner
* removes [email protected] as an owner
* reorders [email protected] as an owner
