Reverted to use of global BUILD_SHARED_LIBS option

Browse Source 
This commit reverts back to exposing the global variable
BUILD_SHARED_LIBS.

Since building static libraries are the default for CMake
(i.e. BUILD_SHARED_LIBS=OFF) the option to build both static and shared
libraries were moved into a conditional option. So the option
PUGIXML_BUILD_SHARED_AND_STATIC is now only visible when the global
BUILD_SHARED_LIBS variable is set to ON.

The change also prevents the case were the user first enables
BUILD_SHARED_LIBS and then enables PUGIXML_BUILD_SHARED_AND_STATIC to
then again disable BUILD_SHARED_LIBS.
