Instead of calling loadDynamicLibraries ourselves, we add the
GDExtension libraries to preload to the "dynamicLibraries" module config
property.
This seems to fix some threading issue with some browsers during the
init phase.
Non-exhaustive list of case-sensitive renames:
GDExtension -> GDNative
GDNATIVE -> GDEXTENSION
gdextension -> gdnative
ExtensionExtension ->Extension (for where there was GDNativeExtension)
EXTENSION_EXTENSION ->EXTENSION (for where there was GDNATIVE_EXTENSION)
gdnlib -> gdextension
gdn_interface -> gde_interface
gdni -> gde_interface
