Fix T84658: Anisotropic BSDF - most modes not using Screen Space

Reflection

Anisotropic is not really supported in Eevee, but since code looks like
it is just intended to make it behave like glossy, it should function
like it too.

Seems like the internal calling from `node_bsdf_glossy` from
`node_bsdf_anisotropic` has swapped arguments.
Also: ssr_id is available for SH_NODE_BSDF_ANISOTROPIC as well (see
`ntree_tag_bsdf_cb`), so why not use it?
