Update endian.h from bionic.
This consolidates the guts of the three endian.h files (endian.h, sys/endian.h, and machine/endian.h) into just sys/endian.h, and turns the others into headers that forward to it. This also consolidates all the architecture specific machine/endian.h files into a single generic header. Finally, this is also the update version of sys/endian.h, which just forwards to compiler builtins rather than implementing it ourselves. Change-Id: Ifce64dc684ce3d3231f3f43a94c083bbd8661840
