Synced from KDE svn: pkg_check_modules() and pkg_search_module() now
both support a QUIET keyword. When given, no messages will be printed (except the REQUIRED ones)
This also fixes#10469 (confusing output of FindLibXml2.cmake)

-use find_package(PkgConfig) instead of include(UsePkgConfig)
-remove the "if already cached make silent" logic, this is already handled by find_package_handle_standard_args()
-remove the if(WIN32) around pkg-config, it shouldn't be necessary

This adds copyright/license notification blocks CMake's find-modules.
Many of the modules had no notices at all. Some had notices referring
to the BSD license already. This commit normalizes existing notices and
adds missing notices.
FIND_PACKAGE_HANDLE_STANDARD_ARGS(), so cmake modules can specify their own
better failure messages. If the default is ok use "DEFAULT_MSG".
Do this also for FindBoost.cmake (#5349)
