Hides many of the implementation details of the wasm-c-api.

Implements memory limiting and execution termination for wasmtime.

Built off of #502.

Always uses prefixed wasmtime-c-api-impl, otherwise the prefixed
implementation bitrots. Prefixes the headers in the repo rule to allow
for globbing, which is not possible in a genrule.

The crates_vendor-provided wasmtime-c-api-impl provided build allows us
to upgrade wasmtime solely by changing the version number in the
Cargo.toml file (and the corresponding repo in bazel/repositories.bzl
for the C headers).

Implements memory limiting and execution termination for wasmtime.

Could you split this off into a separate PR? I think it's just a few lines, so it should be doable, and I think those changes warrant a proper review instead of being bundled in this mass refactor. Thanks!
