feat: Added Makefile for simpler build process

[ChaoticTempest]

Added the Makefile for a simpler build process for users trying to build the SDK.

@ailisp I never got the reason why we went with C, since I was thinking we could've reused the Rust near-sys crate to bind the host functions instead of rewriting it all in C. There's probably a reason behind it, but if we continue to go down the route of using C, we should have a proper build system such as cmake or meson, so people can build the SDK more readily instead of having to manually install dependencies and run into reproducibility issues

@ChaoticTempest jsvm.wasm is essentially a JavaScript runtime plus injected near host functions. The JavaScript runtime is modified QuickJS, which is written in C. To inject near host functions to QuickJS, it also need to be done in C

It's actually not rewriting. It's dealing with QuickJS's encoding/decoding of argument and pass it to near host functions. We don't even need to reuse near-sys crate: in Rust world, a *-sys crate is required as a foreign function interface. In C, simply extern to import them:

extern void read_register(uint64_t register_id, uint64_t ptr);

Looks good to me, I update it with @volovyk-s 's new project layout

Nice @ChaoticTempest! Thanks for the update @ailisp .
It's already good for merging, but we will need to add the ARM (M1) build artifact to the res folder (I will need your help with that).

@itegulov thanks for the help!
