ci: linux: Freeze AppImage binaries

A regression was introduced on May 13 by linuxdeploy that causes file
open dialogs to crash yuzu in the AppImage (likely this commit
1e28ee38fa174279defe70cdaadf2a552c80258c from
linuxdeploy/linuxdeploy-desktopfile). Instead of downloading the latest
version from each of the repos we use to build the AppImage, just
download the ones hosted at yuzu-emu/ext-linux-bin, which are the same
binaries we have been using, but verified to be working and won't update
on us beyond our control.

This can eventually be moved into the container itself to remove the
need to download them at build time.

nvflinger: Create layers when they are queried but not found

core: Make variable shadowing a compile-time error

nifm, ssl: Fix incorrect response sizes

On Linux, build SDL2 from externals with HIDAPI support

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.

main: Add running title's version to window name on EA/mainline

Various improvements to IPC and session management

texture_cache: Handle out of bound texture blits

input_common: Implement SDL motion

Fixes the missing title version number on EA/mainline builds which override the title bar string.

externals: Update mbedtls to 8c88150ca

externals: Checkout 79e8d17024 for FFmpeg

6b6b9e593d does not exist on FFmpeg master, and tag n4.3.1 requires
manually fetching all of FFmpeg's tags. `git` reports that the commit
does not exist initially and can be confusing as a result. Instead,
checkout the immediately previous commit from n4.3.1 on their master
branch.

ssl: Stub Import(Client/Server)Pki

configure_ui: Call RequestGameListUpdate when toggling "Show Add-Ons Column"

- Used in JUMP FORCE Deluxe Edition

hid: Improve hardware accuracy of gestures

- Fixes our error checking of names as well.

- Fixes our move handles implementation to actually move objects.
- Simplifies the traditional IPC path.

- This was not actually closing sessions before.

- This allows us to create a new interface each time ConnectToNamedPort is called, removing the assumption that these are static.
