Tyler Wilding 1f6438e517 deps: update to SDL3 (#3852)
This PR updates to SDL3, and with it, adds a handful of new features.
Everything seems to work but I'm going to look over the code once last
time before merging, some of the API changes are hard to spot.

Fixes #2773

### Pressure sensitivity support for DS3 Controllers

SDL3 adds pressure sensitivity support for DS3 controllers on windows. I
have not tested on linux. The option is disabled by default.

On windows you will need https://docs.nefarius.at/projects/DsHidMini/
and to be using SXS mode.

### DualSense and Xbox One Trigger Effects

If enabled, Jak 2 will have certain trigger effects.  They are:
   - xbox1:
     - small vibrate when collecting dark eco
     - big vibrate when changing to dark jak
     - vibrate when shooting gun, proportional to gun type
   - ps5:
     - resistance when changing to dark jak
     - different gun shooting effects
       - red (resistance)
       - yellow (weapon trigger)
       - blue (vibrates)
       - purple (less resistance)
> **Gun Shooting effects are only enabled if the new "Swap R1 and R2"
option is enabled**

There are more effects that could be used in `dualsense_effects.cpp`,
but I only exposed the ones I needed to OpenGOAL. If a modder wants to
use some of the others and wires them up end-to-end, please consider
contributing that upstream.

### New ImGUI Menu

Added new imgui options for selecting the active controller, for those
people that struggle to select the initial controller.

### Testing

The highlights of what I tested successfully:
   - display
     - [x] all mode switch permutations
     - [x] launch with all modes saved
- [x] switch monitors / unplug monitor that was active, how does it
handle it
     - [x] load with alternate monitor saved and all modes
     - [x] allowing hidpi doesnt break macos
   - controls
     - [x] keyboard and mouse still work
     - [x] pressure sensitivity on linux

PS2

SDL port for the Sony Playstation 2 contributed by:

Credit to

  • The guys that ported SDL to PSP & Vita because I'm taking them as reference.
  • David G. F. for helping me with several issues and tests.

Building

To build SDL library for the PS2, make sure you have the latest PS2Dev status and run:

cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$PS2DEV/ps2sdk/ps2dev.cmake
cmake --build build
cmake --install build

Notes

If you trying to debug a SDL app through ps2client you need to avoid the IOP reset, otherwise you will lose the connection with your computer. So to avoid the reset of the IOP CPU, you need to call to the macro SDL_PS2_SKIP_IOP_RESET();. It could be something similar as:

.....

SDL_PS2_SKIP_IOP_RESET();

int main(int argc, char *argv[])
{
.....

For a release binary is recommendable to reset the IOP always.

Remember to do a clean compilation every time you enable or disable the SDL_PS2_SKIP_IOP_RESET otherwise the change won't be reflected.
