Fix T70121 EEVEE/GPencil: Curves cause crash when using background rendering

This was caused by a faulty initialization of cache->surf_per_mat which
should have been empty.

Refactor readfile's liblink code.

Liblink specific ID type function was so far running a loop over all IDs
of relevant type, unlike almost any other 'ID-callback-like' functions
in Blender, which usually let the looping controll to calling code.

The latter approach is more convinient when one want to add generic
(i.e. type-agnostic) code, since it typically only has to change code in
one place (caller function) instead of tens of places (all the callback
functions).

This commit also changes/sanitizes a few things that had nothing to do
in main liblink code, like mesh conversion from tessfaces to polys
(which can be done in after-linking versionning code), or scenes' cycles
detection/check regarding background 'set' scenes.

Readfile: Proper fix for `recalc` flags clearing in non-real IDs

In current `readfile.c` code we have that:

https://developer.blender.org/diffusion/B/browse/master/source/blender/blenloader/intern/readfile.c$3523

This is unconditionally clearing nodetree's recalc flags, and was added by rB81a762e79f83 ages ago. Thing is, in main ID read code we only clear that flag when **not** in undo context.

This proposed change intends to properly handle those cases, by moving `id.recalc` flags clearing from `read_libblock()` to `direct_link_id()`, which is also called for all 'local' IDs (ntrees and master collections currently).

I?d expect that change to be straightforward (and maybe even fixing some odd undocumented bugs), however there is no .blend file testcases associated with changes in rB81a762e79f83, so wouldn?t mind that to be double checked before it goes to master.
