Added emissions of forward-declarations of types used as names for
specialization constants, which allows to use types declared within
namespaces as specialization constant names.

Moved definition of `SYCLFwdDeclEmitter` to a wider scope to avoid
getting duplicated forward-declarations if there is a spec constant and
a kernel with the same name.
