gcadapter: unbreak build on FreeBSD

 configure_graphics: Prevent unnecessary string copies in UpdateDeviceComboBox()

input_common: Add more libusb error checks for GC Adapter

AM: fix GetDisplayVersion

memory: Race-condition in pagetables.

cpu_interrupt_handler: Remove #pragma once from .cpp file

Port citra-emu/citra#5364: ".github: add a new issue template"

vulkan: Use VK_EXT_extended_dynamic_state when available

Reference libusb doesn't support DragonFly and FreeBSD because those
ship a different libusb implementation (supports 0.1, 1.0, 2.0 API).

configuration: Fix hotkeys that open file dialog in windowed mode

also, in case of failed to get of the basic version, we will try get it from application update.

While we're in the same area, we can make use of qOverload to tidy up
some function pointer casts.

Unlikely to impact performance at all, but this is essentially a "free"
transformation, so why not?

shader_cache: Fix use-after-free and orphan invalidation cache entries

GC Adapter Implementation

externals: Track opus as submodule instead of using conan

gl_buffer_cache: Copy to buffers created as STREAM_READ before downloading

Implement GetKeyCodeMap & GetKeyCodeMap2

Revert "cmake: fix fmt linking"

cmake: fix fmt linking

am: Stub GetIndirectLayerConsumerHandle

acc: ListOpenContextStoredUsers partial stub

Add LR triggers as axes, half press to initiate a press, add GC axis id in config, clarify some code blocks for better readability

maxwell_to_gl: Implement MirrorOnceClampOGL wrap mode using GL_MIRROR_CLAMP_EXT

This fixes some cases where entries could have been removed multiple
times reading freed memory. To address this issue this commit removes
duplicates from entries marked for removal and sorts out the removal
process to fix another use-after-free situation.

Another issue fixed in this commit is orphan invalidation cache entries.
Previously only the entries that were invalidated in the current
operations had its entries removed. This led to more use-after-free
situations when these entries were actually invalidated but referenced
an object that didn't exist.

key_manager: Make use of canonical deleted operator=
