[vcpkg docs] Check for documentation generation in CI (#14614)
* [vcpkg docs] Change how documenting port functions works

Instead of using `##`, use comment blocks for documentation.

Also, add some minor docs and change RST -> MD
so we actually get docs generated.

* add CI stuff

* regenerate docs

* fix vcpkg_find_acquire_program to not use _execute_process

#[===[.md:
# vcpkg_build_cmake
Build a cmake project.
## Usage:
```cmake
vcpkg_build_cmake([DISABLE_PARALLEL] [TARGET <target>])
```
## Parameters:
### DISABLE_PARALLEL
The underlying buildsystem will be instructed to not parallelize
### TARGET
The target passed to the cmake build command (`cmake --build . --target <target>`). If not specified, no target will
be passed.
### ADD_BIN_TO_PATH
Adds the appropriate Release and Debug `bin\` directories to the path during the build such that executables can run against the in-tree DLLs.
## Notes:
This command should be preceeded by a call to [`vcpkg_configure_cmake()`](vcpkg_configure_cmake.md).
You can use the alias [`vcpkg_install_cmake()`](vcpkg_configure_cmake.md) function if your CMake script supports the
"install" target
## Examples:
* [zlib](https://github.com/Microsoft/vcpkg/blob/master/ports/zlib/portfile.cmake)
* [cpprestsdk](https://github.com/Microsoft/vcpkg/blob/master/ports/cpprestsdk/portfile.cmake)
* [poco](https://github.com/Microsoft/vcpkg/blob/master/ports/poco/portfile.cmake)
* [opencv](https://github.com/Microsoft/vcpkg/blob/master/ports/opencv/portfile.cmake)
