Fill out type information for components in C API (#11937)

* Fill out type information for components in C API

I've concluded that I'll want this for wasmtime-py so this fills out
type reflection for various items in the C API. This then additionally
extends the C++ API as well.

prtest:full

* Update crates/c-api/include/wasmtime/component/types/func.h

Simplify C++ binding definitions (#11936)

This commit adds a shared macro to simplify ownership management in the
C++ API and to additionally have a uniform API across types. This is
inspired by the component model work where I felt like I was
copy/pasting quite a lot and wanted to cut down on that.

capi: Add `define_unknown_imports_as_traps` (#11962)

Specifically add this to the component-side of the API to mirror the
functionality for core wasm.

Support resources in the C API of Wasmtime (#11920)

This commit builds on #11885 to build out support for resources in
components in the C API of Wasmtime. Support is effectively the same as
in Rust except more things are behind pointers and `ResourceDynamic` is
used under the hood instead of `Resource<T>` due to the lack of
monomorphization. Tests have been updated to go through some various
situations of ensuring that guest and host resources are representable
and can be manipulated.

Fill out more of the C++ API for components (#11889)

* capi: Add a C++ API for `component::Linker`

Just a bare-bones API for now with functionality that's possible to fill
out. Notably instantiation and defining functions is not yet possible in
C++. Some more feature-parity is also added with the core linkers as
well.

* capi: Add bindings for component instances

* capi: Delete wasip2.h header file

Upon reflection I realize that this is not actually necessary and is
otherwise a duplicate of the functionality in `wasi.h`. All of the
functionality in `wasi.h` is already supported to power WASIp2-defined
APIs in a linker, which is enabled by the `WasiView` trait redirecting
to the `WasiView for WasiP1Ctx` implementation. This is similar to how
the `wasmtime` CLI works where a P1 context is always created and then
it's conditionally used for either core wasm or components.

Effectively this is a deletion of duplicate functionality in the C API
but no underlying functionality is lost. Translating information to
preexisting WASI calls will work the same as using the wasip2 APIs before.

* capi: Start bindings for component functions

* capi: Bind component values in the C++ API

* capi: Finish bindings for component functions/linkers

All the pieces are now in place to use the C++ API in testing.

* Fix compilation of CLI

* Fix compile on MSVC

* Try again to fix msvc compat

* Fix `get_f32` and `get_f64` return values

* Fix signed return values

* Remove no-longer-needed `capi_transfer` function

* Try to fix msvc again

* Remove std::optional constructor of `Val`

* Fix another namespace clash on msvc

* One day I surely may understand a fraction of either C++ or MSVC, but
today is not that day.

* Document internal macro

* Add other internal docs
