Registering a new Symbol with the NameFor() of the source symbol creates a new *named* symbol. When mixing these with unnamed symbols we can have collisions. Update CloneContext::Clone(Symbol) to properly clone unnamed symbols. Update (most) the transforms to ctx.Clone() the symbols instead of registering the names directly. Fix up the tests where the symbol IDs have changed. Note: We can still have symbol collisions if a program is authored with identifiers like 'tint_symbol_3'. This will be fixed up in a later change.
