[resources] Add image bitmap/xml/svg bytearray converters to the corr…

…esponding source sets. (#5098)

The PR adds a method to convert a bitmap bytearray to the ImageBitma, a
vector XML content bytearray to the ImageVector in the common code. And
the same for an SVG files on non-android targets.

<!-- Optional -->

## Release Notes
### Features - Resources
- Added utility functions to decode `Bitmap ByteArray as ImageVector`
and `XML ByteArray as ImageVector` in the common code and `SVG ByteArray
as Painter` in the non-android code
