Try to use pkg-config for detecting libtiff in configure
This is more reliable than checking whether we can link with the library manually and may work even if it's installed in a non-standard location. It also allows the user to specify PKG_CONFIG_PATH='pkg-config --static' when running configure to link with all transitional dependencies when linking statically. Closes https://github.com/wxWidgets/wxWidgets/pull/1073 See #18293.
