Fixed GL_VERTEX_ATTRIB_ARRAY_INTEGER queries

Added pureInteger member to VertexAttribute in order
to keep track of whether the attrib was set using
glVertexAttribIPointer or glVertexAttribPointer and
properly return that state when querying
GL_VERTEX_ATTRIB_ARRAY_INTEGER.

Fixes dEQP-GLES3.functional.state_query.shader.vertex_attrib_integer
