This pull request adds the ability for users to specify input samples
on a per brush basis. The existing field in the main `Paint` struct
forces all brushes of a particular tool type to use the same value.
A new field was added to the `Brush` struct to allow for this value
to be specified there instead, and a corresponding unified value in
`UnifiedPaintSettings` has been created to allow users to use the
same value across all brushes.

Pull Request: https://projects.blender.org/blender/blender/pulls/117080
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
