This commit changes the internal storage and user-facing representation of the brush size values (`size` and `unprojected_size`) from radius to diameter. This has a number of benefits: * While the radius is more helpful for many internal operations, it is more natural to estimate the size of a brush by the diameter * Because the pixel size is stored as an integer, users are currently unable to make brushes that have an odd numbered diameter, notably preventing the ability to make single pixel brushes. Internally, the `Brush` and `UnifiedPaintSettings` size values are versioned to double their on-disk values. The relevant `BKE` functions that access the data return the radius at runtime, and any internal `struct`s that stored radius continue to do so. The 'Radius' text for brushes is changed to 'Size' and all references to it in descriptions are changed to 'size' as well.
