Keymap: update addon register/unregister utilities

Use the same data format and loader that the default key-maps use.

This supports nested properties (needed for macros)
and fixes modal key-maps which weren't supported.

This format still needs to be documented.

Cleanup: move keymap hierarchy into own file

Cleanup: move toolbar keymap generation to bl_keymap_utils

The function is getting complicated, any refactoring
would be best done outside of 'space_toolsystem_common'.

Cleanup: move bpy_extras.keyconfig_utils to own module

bpy_extras were meant to be useful high-level helper functions for
script authors to perform common operations,
to avoid writing to verbose API's.

bpy_extras.keymap_utils contains some specialized API calls
mainly intended for Blender's own internal use.

Move keymap import export to internal API.

Keymap: skip save prompt for default keymap

See T57880

Keymap: only use delete confirmation for X-key

Only use confirmation w/ X-key since this is more likely to be pressed
by accident. Delete-key delete doesn't confirm.

Object: report number of deleted objects

UI: show keyconfig prefs directly under preset

The keyconfig preset and it's preferences were too far apart,
show the preferences under the preset in a collapsible box.

Cleanup: style, unused

Keymap: remove 3ds and maya keymaps

These aren't well maintained and as far as we know
never gained wide adoption.

Remove, we can focus efforts on other key-maps, see: T54963.

WM: remove interaction presets

These only exposed a few options, which didn't end up helping
much to make Blender's key-map fit the behavior of other applications.

Cleanup: gpu docs

Fix problem with onion in multiwindow mode

Fix problem with storage index

The storage index was not updated and the object scale and other data were wrong

Image Empties: Option to not display the backside of image empties

Reviewers: brecht

Differential Revision: https://developer.blender.org/D3964

Fix T57554: texture bake object to active error after recent changes.

UI: hide scene / layer in properties context in some cases, for compactness.

Fix handling of B-Bone custom handle references in Edit mode undo.

Correct a couple of places that should process the handle pointers.

Workbench: Use non-negative lighting evaluation

This makes the lighting a bit more diffuse but don't produce negative
values.

Add a bias of 1.5f to make the lighting a bit more directionnal.

The implementation is based on:
https://github.com/kayru/Probulator/blob/master/Source/Probulator/SphericalHarmonics.h#L136
which is derived from:
http://www.geomerics.com/wp-content/uploads/2015/08/CEDEC_Geomerics_ReconstructingDiffuseLighting1.pdf

The shader implementation is optimized and has the same runtime cost
as previous method:
* no sh eval : 0.13ms
* prev sh eval : 0.14ms
* new sh eval : 0.22ms
* new sh eval opti : 0.14ms

Workbench: Performance: Fix performance drop caused by specular lighting

In my test, the composite pass went from 1.52ms to 0.24ms when specular
lighting is enabled.
