Clean up createSamplerSymbols

The arrayOfStructsSize parameter can always be determined from the TType object, so there's no need to pass it to TType::createSamplerSymbols. Furthermore, it's more natural to do the processing for arrays of structs in TType::createSamplerSymbols, rather than in the TStructure::createSamplerSymbols helper it is using. Also rename some parameter names, and move createSamplerSymbols implementation to Types.cpp. This refactoring change prepares for implementing arrays of arrays.
