GN: Make dEQP import libEGL/libGLESv2 as data_deps.

This removes the hard link dependency on ANGLE. Allows us to use ANGLE
dEQP tests with msan. Otherwise they were complaining about missing
shared libraries. Also would eventually let us test ANGLE dEQP tests
against a native driver.

Was done as a part of investigating SwapBuffers crashes on SwiftShader.
