Auto-format Framework (#160545)
This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.

**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

PinnedHeaderSliver (#143196)
A sliver that remains “pinned” to the top of the scroll view. Subsequent slivers scroll behind it. Typically the sliver is created as the first item in the list however it can be inserted anywhere and it will always stop at the top of the scroll view. When the scrolling axis is vertical, the PinnedHeaderSliver’s height is defined by its widget child. Multiple PinnedHeaderSlivers will layout one after the other, once they've scrolled to the top.

This sliver is preferable to the general purpose SliverPersistentHeader - for its relatively narrow use case - because there's no need to create a [SliverPersistentHeaderDelegate] or to predict the header's size.

Here's a [working demo in DartPad](https://dartpad.dev/?id=3b3f24c14fa201f752407a21ca9c9456).
