When evaluating whether jo.fastmem should be set to true, we check the
value of jo.fastmem_arena. However, due to a change made in 28e8117b90,
jo.fastmem_arena wasn't set until after the first time we set
jo.fastmem, so jo.fastmem would end up always being false until the next
time RefreshConfig was called.

This fixes a problem where changing the JIT debug settings on
Android while a game was running wouldn't cause the changed settings
to apply to code blocks that already had been compiled.
This is done entirely through interpreter fallbacks. It would
probably be possible to implement this using host exception
handlers instead, but I think it would be a lot of complexity
for a rarely used feature, so let's not do it for now.
For performance reasons, there are two settings for this feature:
One setting which does enables just what True Crime: New York City
needs and one setting which enables it all. The latter makes
almost all float instructions fall back to the interpreter.

Converts the remaining PowerPC code over to fmt-capable logging.
Now, all that's left to convert over are the lingering remnants within
the frontend code.
In both cases of the x64 and AArch64 JITs, these would have const casted
away from them, followed by them being placed within an emitter and
having breakpoint instructions written in them.
In this case, we shouldn't be using const period if we're writing to the
emitted data.
Given the code buffer is something truly common to all JIT
implementations, we can centralize it in the base class and avoid
duplicating it all over the place, while still allowing for differently
sized buffers.
This class effectively acted as a "discount vector", that would simply
allocate memory and then delete it in the destructor when it goes out of
scope.
We can just use a std::vector directly to reduce this boilerplate.
Extracts the self-contained code into its own function to clean up the
flow of Jit() a little more.
This also introduces a helper function to HLE.h that will be used to
reduce the boilerplate here and in the interpreter and Jit64 in the
following commits.
This function performs all of the preliminary checks required prior to
attempting to hook/replace a function at a given address. The function then
calls a provided object that satisfies the FunctionObject concept in the
C++ standard library. This can be a lambda, a regular function pointer,
an object with an overloaded function call operator, etc. The only
requirement is that the function return a bool, indicating whether or
not the function was replaced, and that it can take parameters in the
form: fn(u32 function, HLE::HookType type)
Gets rid of the need to construct UReg_MSR values around the the actual
member in order to query information from it (without using shifts and
masks). This makes it more concise in some areas, while helping with
readability in some other places (such as copying the ILE bit to the LE
bit in the exception checking functions).
