arm64/arm64gen: adds a generator sysreggen.go

The assembler needs to support the EL0 and EL1 system registers used
in the MSR/MRS instructions. Because there are many system registers,
this patch adds a generator sysreggen.go. The generator parses the
system register XML files to get the encoding information and writes
them to a $filename file (default "sysRegEnc.go" file). The automatically
generated file is moved to $GOROOT/src/cmd/internal/obj/arm64/ folder
and used by the assembler.
