A32/coprocessor: Remove boost from public interface
...
Removes a boost header from the public includes in favor of using the
standard-provided std::variant.
The use of boost in public interfaces is often a dealbreaker for some
people. Given we use std::optional in the header already, we can
transition over to std::variant from boost::variant.
With this removal, this makes all of our dependencies internal to the
library itself.

A32: Implement ARM-mode CRC32 instructions

Implements the ARM-mode variants of the CRC32 instructions introduced
within ARMv8. This is also one of the instruction cases where there is
UNPREDICTABLE behavior that is constrained (we must do one of the
options indicated by the reference manual).
In both documented cases of constrained unpredictable behavior, we treat
the instructions as unpredictable in order to allow library users to
hook the unpredictable exception to provide the intended behavior they
desire.
