When a valid program is given instead of a shader, an INVALID_OPERATION
is returned rather than INVALID_VALUE when a shader related function is
called. The reverse happens when a program related function is called and
a valid shader program is given to it.

This commit also refactors other places that requires a similar check to
use the same validation function and error message.
