arm64: insn: Add helpers for BTI
In subsequent patches we'd like to check whether an instruction is a
BTI. In preparation for this, add basic instruction helpers for BTI
instructions.
Per ARM DDI 0487H.a section C6.2.41, BTI is encoded in binary as
follows, MSB to LSB:
1101 0101 000 0011 0010 0100 xx01 1111
Where the `xx` bits encode J/C/JC:
00 : (omitted)
01 : C
10 : J
11 : JC
