Expose per-band paint-raster color operations like `raster-saturation raster-contrast raster-brightness-min/max`

Nobody has claimed this yet.

## Motivation

Context is, with [historical-satellite](https://historical-satellite.iconem.com/) I'm comparing different public XYZ/TMS source raster tilesets, and enhancing differences present between two mapbox raster sources. I'm rendering two overlaid maps in two different canvases at , with css clip-path and blending-modes and it would sometimes be useful to preprocess the canvas to apply some sort of histogram equalization, or at least contrast stretching. This way, the blending modes would let the user focus only on large visual change

## Design Alternatives

Following up a long discussion https://github.com/mapbox/mapbox-gl-js/issues/3889 mapbox-gl-js introduced properties `raster-color, raster-color-mix, raster-color-range` implemented in PRs https://github.com/mapbox/mapbox-gl-js/pull/12368 and https://github.com/mapbox/mapbox-gl-js/commit/817fe631d3228c3e732f8f5a8411b66437158891 which are a very great step towards my contrast stretching goal. Great doc [here](https://docs.mapbox.com/style-spec/reference/layers/#paint-raster-raster-color)

## Design

What I'd ultimately like to do is to extend the `raster-color-range` (or eventually `raster-saturation raster-contrast raster-brightness-max`) so they would not only accept a float value, but optionally a float array, which would be exposed per-band, so each RGB channel would have applied a different color-transform.

Under the hood, the current implementation would be akin to passing the same amount/param for each band.

### Concepts

Not sure about which raster paint properties should be exposed as per-band, but being able to do contrast stretching via `raster-color-range or raster-saturation raster-contrast raster-brightness-max` could be very helpful!

### Implementation

In [raster.fragment.glsl](https://github.com/mapbox/mapbox-gl-js/blob/main/src/shaders/raster.fragment.glsl), the fragment shader uniform `u_colorization_scale` (and function `configureRasterColor`) could be passed 3x the current count of params (current min/max is the same for all bands, could be minR, maxR, minG, maxG, minB, maxB

Start with src/shaders/raster.fragment.glsl and the configureRasterColor function, then review the existing raster-color, raster-color-mix, and raster-color-range behavior described in the linked style-spec documentation. Done would mean defining and exposing per-band color operations and passing the required per-band parameters through the raster shader.
