723edb4c06 alignment: Simplify AlignmentAllocator implementation
With C++20, much of the allocator interface has been simplified, so we
can make the same adjustments.

a4306b9e56 Common: remove a mod from AlignUp (#5441)
In cases where the size is not a known constant when inlining, AlignUp<std::size_t> currently generates two 64-bit div instructions.
This generates one div and a cmov which is significantly cheaper.

57ffada746 alignment: Resolve allocator construction issues on debug
This was related to the source allocator being passed into the
constructor potentially having a different type than allocator being
constructed.

We simply need to provide a constructor to handle this case.

This resolves issues related to the allocator causing debug builds on
MSVC to fail.

9aafb2a277 alignment: Specify trait definitions within the allocator
Allows containers and other data structures to consider optimizations
based off of them. We satisfy all of these requirements anyways.

9bede4eeed VM_Manager: Align allocated memory to 256bytes
This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.

345e73f2fe video_core: Use un-shifted block sizes to avoid integer divisions
Instead of storing all block width, height and depths in their shifted
form:

block_width = 1U << block_shift;

Store them like they are provided by the emulated hardware (their
block_shift form). This way we can avoid doing the costly
Common::AlignUp operation to align texture sizes and drop CPU integer
divisions with bitwise logic (defined in Common::AlignBits).

d27f4a4928 common: Move Is4KBAligned() to alignment.h
Aligning on 4KB pages isn't a Switch-specific thing, so this can be
moved to common so it can be used with other things as well.
