[patterns.meta] implement "most used patterns"

What do you think about providing either an additional sub-libraries with some general implementation of the "most used patterns" or providing them directly with patterns.meta. I think that the "most used patterns" will be the ones that are already given in the pattern library. So that would be something like

• horizontal lines, vertical lines, north east lines, north west lines --> Lines
• grid, crosshatch --> Hachures
• dots, crosshatch dots --> Dots
• fivepointed stars, sixpointed stars --> Stars
• bricks --> Bricks
• checkerboard --> Checkerboard

I suggest to use capital names, because this would be consistent to the arrows.meta library. What do you think?

I haven't implemented Bricks and Checkerboard but I don't think they are widely used anyway.

Considering that the total number of questions tagged [tikz-pgf] is 24,295 this seems negligible.

I am ok with this. Thank you for the implementations!!
