Just some tidying up for consistency

d9d59bc1f4 common/cast_util: Declare BitCast and BitCastPointee with the noexcept specifier 
std::bit_cast is also defined with the noexcept specifier, so we can do
the same here to match up with it and stay similar with the standard
library.

std::initializer_list isn't used anywhere in here, and we can just
forward declare the CoprocReg enum to avoid needing to include the

use of dynarmic.

6187de7ca7 a32_interface: std::move UserConfig where applicable 
UserConfig instances contain up to 16 std::shared_ptr<Coprocessor>
instances. We can std::move here to avoid performing 16 redundant atomic
reference increment and decrement operations.

Mostly inconsequential on x64, but we may as well signify intent.

92daae9513 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.

Generally hash functions shouldn't throw exceptions. It's also a

An exception to this rule is made for user-defined specializations,
however we can just be consistent with the standard library on this to
allow it to play nicer with it.

While we're at it, we can also make the std::less specializations
noexcpet as well, since they also can't throw.
