Refactor installation of C API and features supported (#8642)

* Refactor installation of C API and features supported

This commit overhauls and refactors the management of the building of
the C API. Instead of this being script-based it's now done entirely
through CMake and CMake is the primary focus for building the C API. For
example building the C API release artifacts is now done through CMake
instead of through a shell script's `cargo build` and manually moving
artifacts.

The benefits that this brings are:

* The C API now properly hides symbols in its header files that weren't
enabled at build time. This is done through a new build-time generated
`conf.h` templated on a `conf.h.in` file in the source tree.

* The C API's project now supports enabling/disabling Cargo features to
have finer-grained support over what's included (plus auto-management
of the header file).

* Building the C API and managing it is now exclusively done through
CMake. For example invoking `doxygen` now lives in CMake, installation
lives there, etc.

The `CMakeLists.txt` file for the C API is overhauled in the process of
doing this. The build now primarily matches on the Rust target being
built rather than the host target. Additionally installation will now
install both the static and shared libraries instead of just one.
Additionally during this refactoring various bits and pieces of
Android-specific code were all removed. Management of the C toolchain
feels best left in scope of the caller (e.g. configuring `CC_*` env vars
and such) rather than here.

* Don't use `option` for optional strings

* Invert release build check

Also adjust some indentation

* Fix more indentation

Use WASI builder directly in C API (#8572)

* Use WASI builder directly in C API

This commit updates the C API to use the `WasiCtxBuilder` directly
within `wasi_config_t` instead of buffering up the options separately.
This keeps the behavior of the Rust-based API more similar to the C API
and should also help resolve #8552 due to errors being returned more
eagerly in the builder-based API.

This additionally makes some minor modifications to the C APIs here as
appropriate.

Add support for WASI sockets to C API (#5624)

* Add support for WASI sockets to C API

Add support for WASI sockets in the C API by adding a new API to handle
preopening sockets for clients. This uses HashMap instead of Vec for
preopened sockets to identify if caller has called in more than once
with the same FD number. If so, then we return false so caller is given
hint that they are attempting to overwrite an already existing socket
FD.
