[sil] Implement helper function SILType::getFieldType(VarDecl *, SILFunction *) const. This just calls: ``` SILType::getFieldType(VarDecl *, SILModule &, TypeExpansionContext) const ``` using the state in the SILFunction to handle the SILModule and TypeExpansionContext parameters. Just trimming down a larger commit into smaller commits.
