[AIR SDK][Windows][macOS] AIR SDK has WebKit files

[itlancer]

Problem Description

AIR SDK for Windows and macOS has WebKit files but HTMLLoader now legacy and removed.
These files take up disk space but seems are not needed anymore and should be removed from AIR SDK at all.

For example AIR application for Windows has directory
runtimes\air\win\Adobe AIR\Versions\1.0\Resources\WebKit
and file
runtimes\air\win\Adobe AIR\Versions\1.0\Resources\WebKit.dll
which took up about extra 5.5 MB.

Also files perhaps should be remove:
runtimes\air\win\Adobe AIR\Versions\1.0\Resources\NPSWF32.dll
runtimes\air\win\Adobe AIR\Versions\1.0\Resources\NPSWF64.dll

For macOS the similar.

Checked with multiple AIR SDK versions, even with latest AIR SDK 51 for Windows and macOS.
