mgmtd: add our own format definitions for frontend messages

Browse source 
It allows people not familiar with libyang and FRR internals to use
mgmtd FE API by looking only at `mgmt_msg_native.h` header. We still use
the same values to avoid a lot of mapping code, and ensure that any
change doesn't slip unnoticed by using static asserts.
