Merge "Introduce OWNERS for sysui build files" into main

# Build file owners for System UI. Owners should consider the following:

#

#  - Does the change negatively affect developer builds? Will it make

#    the build slower?

#

#  - Does the change add unnecessary dependencies or compilation steps

#    that will be difficult to refactor?

#

# For more information, see http://go/sysui-build-owners
