Upgrade the arm/thumb architecture used by the disassembler

Previously we were using thumbv7 and armv8.1a what ended up showing a
few undefined instruction when disassembling code. This CL update the
architectures used to armv8.2a and thumbv8.2a (newest available) so we
display all instruction in the disassambly.
