Reviewed the code to keep the raylib coding conventions in mind.

Moved the LoadImageSvg() code into LoadImage() guarded by SUPPORT_FILEFORMAT_SVG.
Renamed LoadImageSvgWithSize() to LoadImageSvg().
Added a LoadImageSvgFromString() function to parse the loaded SVG into an actual image. This does the bulk of the work.
