GPencil: Modifier: Simplify: Fix modifier distance and length property feel

This reduce the rate of increase and unlock the range of the props.

GPencil: Modifier: Fix smooth factor range

GPencil: Modifier: Noise: Replace Full Stroke option by Noise Scale

This means the noise can ba scaled along the strokes to create more
varied effects.

GPencil: Fix potential out of bound read in Noise modifier

GPencil: Modifier: Use unique seed for each stroke for Noise modifier

This is needed to avoid the repeating pattern accross duplicated strokes.

GPencil: Modifier: Cleanup Multiple Stroke modifier UI & code

- Reverse Opacity influence.
- Use BLI_listbase function to merge list (fixing a memleak)
- Some minor codestyle changes

Fix T74476: Crash when interpolate GPencil sequence

The stroke totpoints was not updated.

Merge branch 'master' into greasepencil-object

Conflicts:
source/blender/blenkernel/intern/object.c

GPencil: Remove double curve initialization

GPencil: Change Default values and Curve for Noise modifier.

GPencil: Modifier: Rework Array modifier's RNG for better random variation

Use a mix of low decrepency sequence with a special sin rand function
to avoid repeating patterns. This should suffice in most cases

GPencil: Fix missing Noise curve for old files

GPencil: Add Object name to Array and Noise seed generation

GPencil: Fix missing factor adjustment in previous commit

GPencil: Divide old Noise factor to adapt to new logic

The old values were too high.

GPencil: Fix missing break in switch case

GPencil: Fix rebase error

GPencil: Modifier: Improve UI of offset modifier

GPencil: Modifier: Change Noise Modifier behavior

- Noise is applied using a different factor for each property.
- Move Extremes is replaced by a custom curve profile
- Each modifier will create a different result, making stacking possible.
- The result of the position noise will not make the stroke curl.
- Noise default instensity has been tweaked for every property type.

GPencil: More changes to Array randomness

Now the random does not use an array of random values.
