[vcpkg] initial openbsd (community) support (#14549)
* initial openbsd support in vcpkg

* after clang-format

* hardcoded in the preferred compiler for openbsd in bootstrap scipt (thanks @tormfinn)

* Fetch a patched pkg-config because openbsd pkg-config lacks {fcfiledir}

* fixes from review feedback

* corrected hash for pkg-config.openbsd

* re-added missing endif()

* regenerate docs

* Update scripts/cmake/vcpkg_configure_meson.cmake

# vcpkg_common_definitions
File contains helpful variabls for portfiles which are commonly needed or used.
## The following variables are available:
```cmake
VCPKG_TARGET_IS_<target> with <target> being one of the following: WINDOWS, UWP, LINUX, OSX, ANDROID, FREEBSD, OPENBSD. only defined if <target>
VCPKG_HOST_IS_<target> with <host> being one of the following: WINDOWS, LINUX, OSX, FREEBSD, OPENBSD. only defined if <host>
VCPKG_HOST_PATH_SEPARATOR Host specific path separator (USAGE: "<something>${VCPKG_HOST_PATH_SEPARATOR}<something>"; only use and pass variables with VCPKG_HOST_PATH_SEPARATOR within "")
VCPKG_HOST_EXECUTABLE_SUFFIX executable suffix of the host
VCPKG_TARGET_EXECUTABLE_SUFFIX executable suffix of the target
VCPKG_TARGET_STATIC_LIBRARY_PREFIX static library prefix for target (same as CMAKE_STATIC_LIBRARY_PREFIX)
VCPKG_TARGET_STATIC_LIBRARY_SUFFIX static library suffix for target (same as CMAKE_STATIC_LIBRARY_SUFFIX)
VCPKG_TARGET_SHARED_LIBRARY_PREFIX shared library prefix for target (same as CMAKE_SHARED_LIBRARY_PREFIX)
VCPKG_TARGET_SHARED_LIBRARY_SUFFIX shared library suffix for target (same as CMAKE_SHARED_LIBRARY_SUFFIX)
VCPKG_TARGET_IMPORT_LIBRARY_PREFIX import library prefix for target (same as CMAKE_IMPORT_LIBRARY_PREFIX)
VCPKG_TARGET_IMPORT_LIBRARY_SUFFIX import library suffix for target (same as CMAKE_IMPORT_LIBRARY_SUFFIX)
VCPKG_FIND_LIBRARY_PREFIXES target dependent prefixes used for find_library calls in portfiles
VCPKG_FIND_LIBRARY_SUFFIXES target dependent suffixes used for find_library calls in portfiles
VCPKG_SYSTEM_LIBRARIES list of libraries are provide by the toolchain and are not managed by vcpkg
```
CMAKE_STATIC_LIBRARY_(PREFIX|SUFFIX), CMAKE_SHARED_LIBRARY_(PREFIX|SUFFIX) and CMAKE_IMPORT_LIBRARY_(PREFIX|SUFFIX) are defined for the target
Furthermore the variables CMAKE_FIND_LIBRARY_(PREFIXES|SUFFIXES) are also defined for the target so that
portfiles are able to use find_library calls to discover dependent libraries within the current triplet for ports.
