4cdf8b7cfd wasmtime-c-api: Add support for externref values 
This required that `wasm_val_t` have a `Drop` implementation, an explicit
`Clone` implementation, and no longer be `Copy`, which rippled out through the
crate a bit.

Additionally, `wasm_func_call` and friends were creating references to
uninitialized data for its out pointers and assigning to them. As soon as
`wasm_val_t` gained a `Drop` impl and tried to drop the old value of the
assignment (which is uninitialized data), then things blew up. The fix is to
properly represent the out pointers with `MaybeUninit`, and use `ptr::write` to
initialize them without dropping the old data.

b1c7c1401e Fix incorrect scaling for SaveXmm128Far. 
The `SaveXmm128Far` unwind op should have a 32-bit unscaled value.

The value was accidentally scaled down by 16 while calculating whether or not
the `SaveXmm128` or `SaveXmm128Far` unwind op should be used.

3a33749404 Remove 'set frame pointer' unwind code from Windows x64 unwind. 
This commit removes the "set frame pointer" unwind code and frame
pointer information from Windows x64 unwind information.

In Windows x64 unwind information, a "frame pointer" is actually the
*base address* of the static part of the local frame and would be at some
negative offset to RSP upon establishing the frame pointer.

Currently Cranelift uses a "traditional" notion of a frame pointer, one
that is the highest address in the local frame (i.e. pointing at the
previous frame pointer on the stack).

Windows x64 unwind doesn't describe such frame pointers and only needs
one described if the frame contains a dynamic stack allocation.

Fixes #1967.

a7c6433773 wasmtime: Support reference types in the Rust API 
This is a mix of exposing new things (e.g. a `Table::fill` method) and extending
existing support to `externref`s (e.g. `Table::new`).
