Work towards dart-lang/sdk#58729

The lint rule will suggest using a super-parameter for a named parameter
even if the positional parameters cannot be super-parameters.

I'm not sure why unrelated lines were formatted.

…ating at the target position (#182932)

This PR makes animated positioned menus (usually context menus that
treat the whole screen as a menu anchor) begin opening at the user's
pointer rather than the top or bottom of the menu anchor.

Fixes #182929

Before: 


https://github.com/user-attachments/assets/5e536db6-2903-463c-82d1-9f8e8a304bd2

After (the menu closes on left-click, but repositions on right-click,
unless it is external to the red menu anchor surface)


https://github.com/user-attachments/assets/52597be3-2bfe-441c-b962-52b47f69b413

If possible, we should make sure this lands in stable when the menu
animations land in stable.

…nches. (#183470)

Branch creation is restricted in `flutter/flutter` and so GitHub
workflows can't (by default) create any branches on the main repository.
However, the `easy_cp` workflow already works around this by using the
`flutteractionsbot` mirror to host the PR branches. This PR modifies our
workflows to make them in line with the strategy that `easy_cp` uses.

…ffer as when copying buffer -> texture (#183428)

`BlitCopyBufferToTextureCommandGLES` (and initializing/setting texture
contents in `TextureGLES`) supports a bunch of different pixel formats,
as defined in the `TexImage2DData` constructors in
`blit_command_gles.cc` and `texture_gles.cc`.

But `BlitCopyTextureToBufferCommandGLES` only has support specifically
for `kR8G8B8A8UNormInt` and `kB8G8R8A8UNormInt`.

This makes `BlitCopyTextureToBufferCommandGLES` support the same pixel
formats as `BlitCopyBufferToTextureCommandGLES` and `TextureGLES`.

Fixes #183462

## Changes:

### Share `ToPixelFormatGLES`

`blit_command_gles.cc` and `texture_gles.cc` have almost-duplicate logic
to convert `impeller::PixelFormat` to a `GLint internal_format`, a
`GLenum external_format`, and a `GLenum type`. Factor this out into a
shared `ToPixelFormatGLES` function in `formats_gles.h/cc`.

Where there were differences between the `blit_command_gles.cc` and
`texture_gles.cc`:
- `kR32G32B32A32Float`:
- `blit_command_gles.cc` has `internal_format = GL_RGBA`,
`external_format = GL_RGBA`
- `texture_gles.cc` has `internal_format = GL_RGBA32F`, `external_format
= GL_RGBA`
  - I used `internal_format = GL_RGBA32F`, `external_format = GL_RGBA`
- `kR16G16B16A16Float`:
- `blit_command_gles.cc` has `internal_format = GL_RGBA`,
`external_format = GL_RGBA`
- `texture_gles.cc` has `internal_format = GL_RGBA16F`, `external_format
= GL_RGBA`
  - I used `internal_format = GL_RGBA16F`, `external_format = GL_RGBA`
- `kR32Float`:
- `blit_command_gles.cc` has `internal_format = GL_RED`,
`external_format = GL_RED`
- `texture_gles.cc` has `internal_format = GL_R32F`, `external_format =
GL_RGBA`
  - I used `internal_format = GL_R32F`, `external_format = GL_RED`

All the other PixelFormat cases were the same between the two files and
copied over directly.

### Remove `TexImage2DData`

`blit_command_gles.cc` and `texture_gles.cc` each define a
`TexImage2DData` struct which just contains the pixel format data and
sometimes an optional data buffer. I removed both of these. Instead, we
just use the `ToPixelFormatGLES` return value directly, and use the
source data buffer directly.

### Improve pixel format support in
`BlitCopyTextureToBufferCommandGLES::Encode()`

In `BlitCopyTextureToBufferCommandGLES::Encode()`, use
`ToPixelFormatGLES()` to determine the format and type used for
`gl.ReadPixels()`. This expands the existing functionality that only
supported two specific pixel formats.
