EmuWindow::PollEvents was called from the GPU thread (or the CPU thread
in sync-GPU mode) when swapping buffers.  It had three implementations:

- In GRenderWindow, it didn't actually poll events, just set a flag and
  emit a signal to indicate that a frame was displayed.

- In EmuWindow_SDL2_Hide, it did nothing.

- In EmuWindow_SDL2, it did call SDL_PollEvents, but this is wrong
  because SDL_PollEvents is supposed to be called on the thread that set
  up video - in this case, the main thread, which was sleeping in a
  busyloop (regardless of whether sync-GPU was enabled).  On macOS this
  causes a crash.

To fix this:

- Rename EmuWindow::PollEvents to OnFrameDisplayed, and give it a
  default implementation that does nothing.

- In EmuWindow_SDL2, do not override OnFrameDisplayed, but instead have
  the main thread call SDL_WaitEvent in a loop.

logging/settings: Increase maximum log size to 100 MB and add extended logging option

CI: move refreshenv to the configure step

... so that cmake can find the Vulkan SDK binaries

patch_manager: Remove usages of the global system instance

gl_rasterizer: Make floating-point literal a float

async_shaders: std::move data within QueueVulkanShader()

ci: install Vulkan SDK in MSVC build

core: Make nvservices more standardized

gl_rasterizer: Remove warning of untested alpha test

Alpha test has been proven to only affect the first render target.

shader_bytecode: Eliminate variable shadowing

hle: service: Stub OLSC Initialize and SetSaveDataBackupSettingEnabled functions.

Same behavior, but constructs the threads in place instead of moving
them.

This is equivalent to moving all the contents and then clearing the
vector. This avoids a redundant allocation.

Same behavior, but avoids redundant copies.

While we're at it, we can simplify the pushing of the parameters into
the pending queue.

Gets rid of an unnecessary expansion from float to double.

Ensures that all queried values are made use of.

configure_input_player: Use static qualifier for IsProfileNameValid()

Modify rumble amplification

common/bit_cast: Add function matching std::bit_cast without constexpr

maxwell_3d: Move code to separate functions and insert instead of push_back

Add a std::bit_cast-like function archiving the same runtime results as
the standard function, without compile time support.

This allows us to use bit_cast while we wait for compiler support, it
can be trivially replaced in the future.

virtual_buffer: Do nothing on resize() calls with same sizes

- Used by Animal Cross: New Horizons v1.6.0 update, minimal stub gets this update working.

Prevents us from churning memory by freeing and reallocating a memory
block that would have already been adequate as is.

page_table: Allow page tables to be moved

With this, only 19 usages of the global system instance remain within
the core library.

We're almost there.

This is a static member function, so we don't need use an existing
instance to call this function.

Project Mjölnir: Part 3 - Controller Profiles and Vibration Rework

VirtualBuffer makes use of VirtualAlloc (on Windows) and mmap() (on
other platforms). Neither of these ensure that non-trivial objects are
properly constructed in the allocated memory.

To prevent potential undefined behavior occurring due to that, we can
add a static assert to loudly complain about cases where that is done.

Makes page tables and virtual buffers able to be moved, but not copied,
making the interface more flexible.

Previously, with the destructor specified, but no move assignment or
constructor specified, they wouldn't be implicitly generated.

Resolves two -Wdocumentation warnings.

Prevents indirect inclusions for these headers.

[gpu, render_base, rasterizer_interface]: Make use of [[nodiscard]] where applicable
