Add more CLI flags for wasm features #917

This commit adds a few more flags to enable wasm features via the CLI,
mirroring the existing --enable-simd flag:

  • --enable-reference-types
  • --enable-multi-value
  • --enable-threads
  • --enable-bulk-memory

Additionally the bulk memory feature is now automatically enabled if
reference-types or threads are enabled since those two proposals
largely depend on bulk-memory.

Should we have an --enable-all too, like wabt does?

Some of this originated in bytecodealliance#917 but nowadays it shouldn't be necessary
to control proposals like this. Instead it's probably best nowadays to
throw configuration at `wasmparser` and use its definition of features
to determine whether constructs make sense or not. This reduces the
amount of bits and pieces Wasmtime has to do and avoids interactions
such as bytecodealliance#9622.

Closes bytecodealliance#9622
