this basically allows the threads to exist in these logical CPUs, undisturbed, and without trashing each other's cache
this could improve performance, very tricky thing to pull off correctly, but again, this is mostly an experiment
will mainly benefit: Linux, Android, FreeBSD, Windows (not ARM)
Additionally, this means no context trashing :)

Now that we have most of core free of shadowing, we can enable the
warning as an error to catch anything that may be remaining and also
eliminate this class of logic bug entirely.
- With using unique_ptr instead of shared_ptr, we have more explicit ownership of the context.
- Fixes a memory leak due to circular reference of the shared pointer.
Removes all remaining usages of the global system instance. After this,
migration can begin to migrate to being constructed and managed entirely
by the various frontends.
- In `SetCurrentThreadName`, when on Linux, truncate to 15 bytes, as (at
least on glibc) `pthread_set_name_np` will otherwise return `ERANGE` and
do nothing.
- Also, add logging in case `pthread_set_name_np` returns an error
anyway. This is Linux-specific, as the Apple and BSD versions of
`pthread_set_name_np return `void`.
- Change the name for CPU threads in multi-core mode from
"yuzu:CoreCPUThread_N" (19 bytes) to "yuzu:CPUCore_N" (14 bytes) so it
fits into the Linux limit. Some other thread names are also cut off,
but I didn't bother addressing them as you can guess them from the
truncated versions. For a CPU thread, truncation means you can't see
which core it is!
