Draft: 3013367: Add missing effects & their migrations

Closes #3013367

Adds the following effects from the D7 module:

• coloractions_brightness => image_effects_brightness
• coloractions_colorshift => image_effects_color_shift
• coloractions_convert => convert
• coloractions_inverse => image_effects_invert
• coloractions_posterize => image_effects_posterize
• imagecache_adjustlevels => adjustLevels
• imagecache_alpha => image_effects_adjust_alpha (note: the ImageMagick function wasn't provided in the D7 module, and either the GD or ImageMagick function are wrong as they give different results)
• imagecache_colormultiply => image_effects_color_multiply
• imagecache_coloroverlay => image_effects_color_overlay
• imagecache_desaturatealpha => image_effects_desaturate_alpha
• imagecache_removeanimation => image_effects_remove_animation

Adds the following migrations:

• canvasactions_aspect
• canvasactions_canvas2file
• canvasactions_definecanvas
• canvasactions_resizepercent
• coloractions_brightness
• coloractions_colorshift
• coloractions_convert
• coloractions_inverse
• coloractions_posterize
• imagecache_adjustlevels
• imagecache_alpha
• imagecache_autorotate
• imagecache_colormultiply
• imagecache_coloroverlay
• imagecache_desaturatealpha
• imagecache_removeanimation

Still needs tests for the newly added effects.
