[Piers] Add game.shader.presets

[garbear]

Description

As title says, this adds game.shader.presets to the list of add-ons for the Piers branch.

I put "all" for platforms to see what it builds on. Or, we can decide which platforms we want instead.

Motivation and Context

Needed after xbmc/xbmc#26435.

How has this been tested?

This commit has been in my RetroPlayer builds since 2017.

• Specifying “all” will trigger builds on every platform, including those that may not be supported or tested. Consider listing only the platforms where this add-on has been verified to avoid CI failures or unnecessary build time.

Add a trailing newline to this file to comply with POSIX text file conventions and ensure any scripts parsing it handle the final line correctly.

Similarly, add a trailing newline here to conform with standard text file formatting and prevent potential parsing issues in the add-on registry loader.

Do we care about the newline?
