Fix: Sequencer timecodes was using wrong properties

- The Start value and the Playhead value both used 'frame_start', which only tells you where the strip was originally inserted. Instead 'frame_final_start' is now used, which results in the correct timeline values.
- When scaling the sidebar some of the the labels weren't scaling correctly, this has been fixed
- Use Hold Cut/Cut instead of Hard/Soft Cut, for consistency

Fix "Fix Deform" not working in Blender 2.8

Need to copy changes to the evaluated mesh before requesting
new deformed mesh.

Tested on a file from T32406.

Fix "Fix Deform" access evaluated data form original objects

This is part of T60517.

Set Node Editor to use Box Select tool by default

This makes Shift and Ctrl work properly to extend and subtract selections.
This also moves Cut Links to Ctrl-RMB, which doesn't conflict with the selection tool.

Cleanup: clang-format

GPencil: Reorganize blend shader

Reorganize code and change some functions to mimic other softwares blend modes. Still need more work.

GPencil: Remove blend_opacity from shader

The opacity was already used and using it in the shader only duplicate the blend.

Particle system: Move runtime data to runtime field

Allows it to be preserved during copy-on-write update when on-geometry
related update is needed.

This is a required part for T63537, where we need to preserve the entire
evaluation data when object is tagged for only RECALC_COPY_ON_WRITE.

Clear Datablocks Preview: add some more generic options.

Sometimes one may want to nuke all previews altogether, running the
operator for all eight individual ID types would be tedious then...

Fix T65034: Viewing material calls frame update handler

Use lower level dependency graph evaluation which doesn't run any handlers,
doesn't touch sound system, doesn't inform image editors about changes.

Should probably move such evaluation steps to a helper function in DEG module,
but that is more like a cleanup.

Cleanup: correct wireframe xray flag name

Revert part of d56c0a0a6affcdfd7335c

Cleanup: clang-format

Cleanup: tweak logic for skipping modules

Startup is the special case, so match against this instead of 'modules'.

Hide from UI overridable option for custom properties.

Fix T57489: Texture coordinate object reference not updating in Eevee

GPencil: Fix clamp alpha problems when using Regular blend

The problem was the alpha was not premult and the opacity factor was applied two times.

Typos in description

Compositor: fix linear feather falloff in dilate/erode node

The bug only affected debug builds.

Fix T65741: Removing a GPencil Object's Material Slot deletes the strokes assigned to it

This was a design decision, but now we have decided to change it using the active material for the strokes using deleted material.

If the material slot is empty a new material is created to keep the strokes visible.

Fix T64930: FFmpeg Output- no color mode by default

The issue was that the valid color modes was checked on the old image
format, not the new one. So if you switched formats it would not
correctly check if the settings were valid.
