Implement user-specified pixel shaders, redux (#8565) 
Co-authored-by: mrange <marten_range@hotmail.com>

I loved the pixel shaders in #7058, but that PR needed a bit of polish
to be ready for ingestion. This PR is almost _exactly_ that PR, with
some small changes.

* It adds a new pre-profile setting `"experimental.pixelShaderPath"`,
  which lets the user set a pixel shader to use with the Terminal.
    - CHANGED FROM #7058: It does _not_ add any built-in shaders.
    - CHANGED FROM #7058: it will _override_
      `experimental.retroTerminalEffect`
* It adds a bunch of sample shaders in `samples/shaders`. Included: 
    - A NOP shader as a base to build from.
    - An "invert" shader that inverts the colors, as a simple example
    - An "grayscale" shader that converts all colors to grayscale, as a
      simple example
    - An "raster bars" shader that draws some colored bars on the screen
      with a drop shadow, as a more involved example
    - The original retro terminal effects, as a more involved example
    - It also includes a broken shader, as an example of what heppens
      when the shader fails to compile
    - CHANGED FROM #7058: It does _not_ add the "retroII" shader we were
      all worried about.
* When a shader fails to be found or fails to compile, we'll display an
  error dialog to the user with a relevant error message.
    - CHANGED FROM #7058: Originally, #7058 would display "error bars"
      on the screen. I've removed that, and had the Terminal disable the
      shader entirely then.
* Renames the `toggleRetroEffect` action to `toggleShaderEffect`.
  (`toggleRetroEffect` is now an alias to `toggleShaderEffect`). This
  action will turn the shader OR the retro effects on/off. 

`toggleShaderEffect` works the way you'd expect it to, but the mental
math on _how_ is a little weird. The logic is basically:

```
useShader = shaderEffectsEnabled ? 
                (pixelShaderProvided ? 
                    pixelShader : 
                    (retroEffectEnabled ? 
                        retroEffect : null
                    )
                ) : 
                null
```

and `toggleShaderEffect` toggles `shaderEffectsEnabled`.

* If you've got both a shader and retro enabled, `toggleShaderEffect`
  will toggle between the shader on/off.
* If you've got a shader and retro disabled, `toggleShaderEffect` will
  toggle between the shader on/off.

Closes #7013

Closes #3930 "Add setting to retro terminal shader to control blur
radius, color" 
Closes #3929 "Add setting to retro terminal shader to enable drawing
scanlines" 
     - At this point, just roll your own version of the shader.
