[osgearth]add featurs examples and controls

Fixes #44303

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

Is it necessary to add so much code for examples?

[yanzixiang]

i'am sorry,i can not find an easy method to del the exe files and keep the dll files in the same dir, so i have to hard code it.
