wasm-c-abi: llvm fix struct handling + reorganize
...
I changed to `wasm/abi.zig`, this design is certainly better than the previous one. Still there is some conflict of interest between llvm and self-hosted backend, better design will appear when abi tests will be tested with self-hosted.

wasm: fix abi size of c_longdouble
...
According to https://github.com/WebAssembly/tool-conventions/blob/main/BasicCABI.md
the size of c's long double is 16 bytes for Wasm, rather than 8 bytes
which was the value previously in the compiler. This ensures
we not only pass the correct value, but also creates the correct
function signature needed to pass the Wasm validator.
This also adds an additional test case in c_abi tests.
