ReinUsesLisp 7bd603061c tests: Add unit tests for the GPU range tracking buffer container
Due to how error prone the container design is, this commit adds unit
tests for it.

Some tests taken from here are based on bugs from using this buffer
container in games, so if we ever break it in the future in a way that
might harm games, the tests should fail.

ReinUsesLisp 3fdb42e0b4 tests: Fix data race in fibers test
Previous to this commit, the tests were using operator[] from
unordered_map to query elements but this silently inserts empty elements
when they don't exist. If all threads were executed without concurrency,
this wouldn't be an issue, but the same unordered_map could be written
from two threads at the same time. This is a data race and makes some
previously inserted elements invisible for a short period of time,
causing them to insert and return an empty element. This default
constructed element (a zero) was used to index an array of fibers that
asserted when one of them was nullptr, shutting the test session off.

To address this issue, lock on thread id reads and writes. This could be
a shared mutex to allow concurrent reads, but the definition of
std::this_thread::get_id is fuzzy when using non-standard techniques
like fibers. I opted to use a standard mutex.

While we are at it, fix the included headers.

Lioncash e1ab72a0ea tests/core_timing: Remove pragma optimize(off)
I made a review comment about this in the PR that this was introduced
in (#3955, commit 71c4779211), but it
seems to have been missed.

We shouldn't be using this pragma here because it's MSVC specific. This
causes warnings on other compilers.

The test it's surrounding is *extremely* dubious, but for the sake of
silencing warnings on other compilers, we can mark "placebo" as volatile
and be on with it.

Lioncash a7af349dae core_timing: Make use of uintptr_t to represent user_data
Makes the interface future-proofed for supporting other platforms in the event we ever support platforms with differing pointer sizes. This way, we have a type in place that is always guaranteed to be able to represent a pointer exactly.

Lioncash 323680e5ad core/memory: Migrate over memory mapping functions to the new Memory class
Migrates all of the direct mapping facilities over to the new memory
class. In the process, this also obsoletes the need for memory_setup.h,
so we can remove it entirely from the project.

core_timing: Use better reference tracking for EventType. (#3159)
* core_timing: Use better reference tracking for EventType.

- Moves ownership of the event to the caller, ensuring we don't fire events for destroyed objects.
- Removes need for unique names - we won't be using this for save states anyways.

Fernando Sahmkow 90792cdb6e Core_Timing: Make core_timing threadsafe by default.
The old implementation had faulty Threadsafe methods where events could
be missing. This implementation unifies unsafe/safe methods and makes
core timing thread safe overall.

Lioncash 8e510d5afa kernel: Make the address arbiter instance per-process
Now that we have the address arbiter extracted to its own class, we can
fix an innaccuracy with the kernel. Said inaccuracy being that there
isn't only one address arbiter. Each process instance contains its own
AddressArbiter instance in the actual kernel.

This fixes that and gets rid of another long-standing issue that could
arise when attempting to create more than one process.

Lioncash bd983414f6 core_timing: Convert core timing into a class
Gets rid of the largest set of mutable global state within the core.
This also paves a way for eliminating usages of GetInstance() on the
System class as a follow-up.

Note that no behavioral changes have been made, and this simply extracts
the functionality into a class. This also has the benefit of making
dependencies on the core timing functionality explicit within the
relevant interfaces.

Lioncash 5c0408596f kernel/thread: Use a regular pointer for the owner/current process
There's no real need to use a shared pointer in these cases, and only
makes object management more fragile in terms of how easy it would be to
introduce cycles. Instead, just do the simple thing of using a regular
pointer. Much of this is just a hold-over from citra anyways.

It also doesn't make sense from a behavioral point of view for a
process' thread to prolong the lifetime of the process itself (the
process is supposed to own the thread, not the other way around).
