WifiLogger: use R for ring buffer sizing

Use Resources to determine ring-buffer sizing.
This is to support board-specific ring-buffer
sizes.

BUG=29225988
TEST=unit tests
TEST=manual

Manual test (bullhead): Added some Log.e() statements,
and verified that RING_BUFFER_BYTE_LIMIT_SMALL and
RING_BUFFER_BYTE_LIMIT_LARGE were 32KB and 1024KB,
respectively.
