Update 3rd party lib references (#19959)

* Added RenderTexture::saveToFileAsNonPMA() to save images without PMA.
Set the PMA parameter to true when calling initWithRawData() inside RenderTexture::newImage(), since textures are PMA.
Renamed Image::premultipliedAlpha() to Image::premultiplyAlpha() to better reflect it's action, and made it public.
Added Image::reversePremultipliedAlpha() to allow the reversing of the PMA.
Updated CCImage-ios.mm to set the correct bitmapInfo for PMA and non-PMA images before saving a file.
Updated RenderTextureTest::RenderTextureSave() to cater for non-PMA file saving.

* [CCImage-ios.mm] Fixed indentation.

* Update to v3-deps-159
