Recognize new package prefix directory variable in CMake 3.29.1.

[teo-tsirpanis]

In CMake 3.29.1, the configure_package_config_file function changed the name of the variable with the package prefix dictionary from PACKAGE_PREFIX_DIR to a name that depends on the current package's name, and a counter variable. This PR updates the vcpkg_cmake_config_fixup function accordingly to recognize this new pattern.
