emscripten: Add JS library dependencies using EM_JS_DEPS macro

[sbc100]

See emscripten-core/emscripten#19780

[icculus]

Oh wow, I've been bit by this problem myself; EM_JS_DEPS is going to be a life-saver for sure. :)

I saw this was force-pushed a few times; let me know when you're done and I'll merge this!

[sbc100]

I'm done if the CI passes!

[icculus]

GitHub seems to be having a build-farm issue at the moment, but we'll get this in when they fix it. :)

Are the changes not needed in SDL3 ?

[icculus]

Oh, whoops, I thought this was SDL3. I'll cherry-pick it over.

[sbc100]

Oh, whoops, I thought this was SDL3. I'll cherry-pick it over.

Sorry, whats the policy on committing to with SDL2 vs main branch?

[slouken]

In general development goes into SDL3, and is cherry picked into SDL2, but we're flexible.

[icculus]

This is in for SDL3 in b42cb1c; should we kick this into 2.28.2, as well?

[slouken]

No, let's leave it as-is for 2.28.1 unless it's critical.

[ericoporto]

I think this is safe to merge in release-2.28 branch so it gets in a 2.28.5 release.

[slouken]

This is already in the 2.28.4 release.

This is already in the 2.28.4 release

Ah, ok, found the commit, it was in September:
