* [vcpkg] add missing implib definitions, fix shared lib extension on mac

(cherry picked from commit 2cddef9541202ecc01ad43036575bc606dc01117)

* Better find_library suffixes and prefixes.

* moved additional suffix into a comment and reverted back to what is expected on windows

* updated documentation for add variables.

## # 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. only defined if <target>
## 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
## ```
##
## 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.
##
