Reduce deps

[Et7f3]

This PR remove dependencies on refmterr (used only at build time) and esy-cmake 👀 I wonder why it was their.

Rationale: I have low disk space on my linux partition so try to reduce revery size globally. Another reason: less dependencies mean more easier to update. Now to publish to opam we need to publish our patched esy-sdl2 and this package is ready.

I have force pushed because I have forgotten to remove dune@<2.1 to test [email protected]

• Works when linked locally to Revery
• Example runs (esy @example run)

However, trying to build with esy @js fails with:

Should we do something about the JS-build? @Et7f3

[Et7f3]

I really don't know what happen here. I will try to investigate after.

[Et7f3]

@lessp on master can you add: "@opam/lwt_ppx": "^2.0.0",

[Et7f3]

We had similar issuer with sdl https://discordapp.com/channels/526111832478449695/532721901886504981/676493496575590417

[lessp]

"@opam/lwt_ppx": "^2.0.0"

Can confirm it builds on master when adding this to js.json

Ok I am rebasing because a unused deps was already removed d679957
