This reverts commit 5e0aa8b9.

Currently taking a screenshot in release mode crashes and is also not documented as a supported command. Fix both of these and add test cases.

This reverts commit 4fde217d.

They appear to be passing now.

Almost all of the flag setup on Linux, macOS, and Windows should be
identical; this pulls that common setup to a shared method.

This adds support for several flags on macOS that have all the necessary
plumbing already in place due to shared backend code, but were never
enabled.

Fixes https://github.com/flutter/flutter/issues/64944

Fix typo.

People frequently assume they can run the executable they find at the
top level of the build directory, and don't understand why they get
resource errors from the engine. To avoid that, this puts the unbundled
copy of the executable in a subdirectory with a name that should warn
people away from running it.

Fixes #64963
