Get sample working with wasm

By combining the wasm functionality in SpaceGame with the SDL3 library this now works on wasm32 target.

Nice, I likelx wont have time to review it before saturday though

Did you actually compile this ?

From what ive found emscripten currently does not have a sdl3 port.
Instead users can build the libSDL3.a file and link it from the library file.
Also the linker flags dont seem to be required.

okay the emscripten repo has it available, just the version downloaded by BeefIDE doesnt

[SlateyDev]

yes, I possibly could have mentioned that so you didn't have to do the runaround yourself. i downloaded a newer version of emscripten which included SDL3 support.

I will be leaving this hanging here until the version distributed by BeefIDE gets updated.
Until then users who want to build sdl3 to wasm should manually install the newest emscripten version and can then use this pr.
