DwM: optimize mesh batch conversion

- Replace GWN_vertbuf_attr_set with Gwn_VertBufRaw & GWN_vertbuf_raw_step
to avoid intermediate copy.
- Avoid extra conversion step with: float[3] -> short[3] -> Gwn_PackedNormal.
We can skip the short[3].

Gives approx 6% speedup here.

Gawain: add method of stepping over data directly

This avoids using GWN_vertbuf_attr_set which needs to calculate the
offset and perform a memcpy every call.

Exposing the data directly allows us to avoid a memcpy in some cases
and means we can write to the vertex buffer's memory directly.

Gawain: Use common prefix for packed normal

Merge branch 'master' into blender2.8

Fix T51926: Selecting pose icon under expanded group in outliner causes crash.

Cannot switch uninstantiated armature to Pose mode...

DwM: no need to calculate face normal

Cleanup: quiet negative shift warning

DwM: add CD_AUTO_FROM_NAME for mesh conversion

Fix crash & performance regression w/ base lookup

Was doing O(n^2) list lookups with blender-render drawing & transform.
Also missing NULL checks would crash.

Use Object.base_flag (already used by new draw manager in places)
to avoid list lookup.

Note, transform still performs inefficient lookups,
but only for selected parents (like 2.7x), not all parents.

Eevee: Add Initial support for Principle BRDF.

Lots of things not working yet but it's comming.

Eevee: Remove ShadingData struct.

That was a bad idea after all.

Fix assert calculating tangents with no faces

GPUTexture : Un-clamp float rect datas.

We do not need it anymore because we do not use glu anymore. And we need full range for HDRI Lighting.

Fix T51909: Cycles: Uninitialized closure normals for the Hair BSDF

As the title says, the normal wasn't set for the Hair BSDF because it wasn't
needed before. However, the denoiser uses it to store the feature passes, so
it needs to be set now.

GPU_codegen: Fix geometry shader.

GPU_codegen: Add support for passing attributes through the geometry stage.

Should fix some issues with missing attributes in Eevee.

Fix node UI not using translation context correctly.

Now that some node types may have custom context, we need to handle that
in the (convoluted :| ) UI code of nodes as well.

Reported in T43295 by Gabriel Gazz�n (@gab3d), thanks.

Eevee: Fix shader linking error.

Eevee: Fix Shadow Map bug: fix T51924

Eevee: Fix Shader compilation on certain driver.
