Accept GL_TEXTURE_MAX_ANISOTROPY_EXT for samplers.

This usage is not explicitly specified in EXT_texture_filter_anisotropic,
but in practice all notable ES 3.0 implementations treat maximum anisotropy
as sampler state. Furthermore, it's already accepted as a valid sampler
parameter by ValidateSamplerObjectParameter in Context.cpp.

This avoids a crash when calling
glSamplerParameteri(sampler, GL_TEXTURE_MAX_ANISOTROPY_EXT, 1.f);
