3638dba855 examples: Run the correct example executable on Windows 
We were accidentally always running the `fib-debug/main` example because of
shenanigans with alphabetical ordering and hard coding "main.exe" as the command
we run. Now we properly detect which example we built and run the appropriate
executable.

9f0ec620f0 wasmtime-c-api: Remove duplicate tests of examples 
The canonical examples tests will be the examples run via `cargo run -p
run-examples` from now on. Those tests have two advantages over the ones being
deleted:

1. They will automatically pick up new examples and run/test them.
2. They support all of Linux, MacOS, and Windows, while the tests being deleted
   are Linux only.

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.

Part of #929

f316bef763 machinst aarch64: fix encoding generation of left-shift by 0; 
The ARM book says that the immr field should contain (-count % 64); the
existing code was approximating this with (64 - count), which is not
correct for a zero count.

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.
