[libpng16] chore: Update .gitignore

Ignore artifacts produced by IDEs such as Embarcadero RAD Studio,
JetBrains Fleet, Qt Creator, and possibly others.

Also update the list of artifacts produced by C/C++ workflows and
CMake workflows in Microsoft Visual Studio and Qt Creator.

This is a cherry-pick of commit 10c76f3
from branch 'libpng18'.
