d4e7676daa ebiten: do not use mipmaps at DrawTrianglesShader 
This change stops using mipmaps at DrawTrianglesShader. Though this
is a brekaing change, the shader APIs are experimental in v2.4, and
the extent of the impact should be pretty small as DrawTrianglesShader
is a rarely-used low-level API.

For DrawRectShader, mipmaps were not used even before this change.

f293a03ab6 internal/mipmap: reland: do not consider filter to determine mipmap level 
This is a reland of 42833614fb.

Now the filter argument is not used (a4e9a05b14),
the filter value can be the nearest filter even though the shader is
for the linear filter.

As long as `canSkipMipmap` is set correctly, we don't have to consider
the parameter `filter`. We should ignore it.

a4e9a05b14 ebiten: reland: use Kage shaders instead of built-in shaders for a color matrix 
This replaces the built-in shaders with Kage shadres. This is a
refactoring and doesn't degrade performance:

```
go test -bench=^BenchmarkColorMScale$ -run=^$ . -count=5
```

```
name           old time/op  new time/op  delta
ColorMScale-8   978ns ±15%  1184ns ±46%   ~     (p=0.413 n=4+5)
```

A follow-up change to remove the built-in shaders is needed.

Closes #2364

520c47f0e8 Revert "ebiten: use Kage shaders instead of built-in shaders for a color matrix" 
This reverts commit 7fc79c50c3.

Reason: a color scale might be used with ColorM (DrawTriangles)

bac34a4474 ebiten: add NewImageWithOptions and NewImageOptions 
This change adds NewImageWithOptions, that creates a new image with
the given options.

NewImageWithOptions takes image.Rectangle instead of a width and a
height, then a user can create an image with an arbitrary bounds.
A left-upper position can be a negative number.

NewImageWithOptions can create an unmanged image, that is no longer
on an automatic internal texture atlas. A user can have finer controls
over the image.

This change also adds tests for this function.
