GPencil: Adapt edit mode operators for curve edit

Change the rest of the edit mode opearators (c62bc08f) so that they

Fix T78579: Proxy produces wrong preview when using Offset or Crop

Make sure that proxy and original images are scaled to same size before
applying offset or crop.

During testing, I discovered, that raw cache will lose information whether
this image was proxy or not. Because of this, proxy images will not create
this cache type. It would be fairly easy to implement this functionality for
cache, but I have decided to not do it now, because I did not want to pass yet
another mostly hard-coded bool flag to cache system. Since image is proxy, it
should be fast to read anyway.

In case of using offset property, code was modified to make sure we scale
image only once. I also tried to make code more readable and streamlined and
cleaned up surrounding functions a bit.

BLI: add C++ random number generator

This adds `blender::RandomNumberGenerator` in `BLI_rand.hh`.
Furthermore, `RNG` is now implemented in terms of this new generator.
No functional changes are expected, the generated random numbers
are not changed by this commit.

Expose override flags to python RNA properties definition.

Time will tell whether we need to expose more RNA override flags here.

Refactor override code to properly deal with runtime rna properties too.

The triplet static RNA / runtime RNA / custom properties is a real pain to
deal with...

Using the new `PropertyRNAOrID` struct helps clarifying and properly
dealing with all three cases.

Note that this makes override of py-defined RNA properties working
(support for that will be committed next).

RNA: refactor how we get 'ensured' RNA properties.

Introduce new PropertyRNAOrID structure, storing most useful data about
an 'opaque' PropertyRNA in relation with a given PointerRNA struct.

It deals with all the three cases (pure static RNA, runtime RNA where
data is actually stored in IDProperties, and pure IDProperties, aka
custom data.
