Primitive restart fixed

SwiftShader wasn't correctly handling having no restart indices
in the index buffer while having primitive restart enabled. In
the WebGL 2 conformance tests, the reference image is also
computed while primitive restart is on, which means that
Context::drawElements() may modify the internal primitive type,
so indices must be adjusted to reflect that change, even if no
restart indices are present in the index buffer.

Fixes all WebGL 2 tests in:
all/deqp/functional/gles3/primitiverestart
