Candera Text Engine

Several text render cache related issues were fixed. This includes upload count and upload/unload call fixes for textures (CGI1-30284). 
 Fixed issues when building Monotype on Integrity systems (CGI1-39895). 
 Fixed Monotype cache item as custom width have not always been cached correctly (CGI1-34207). 
 Removed differences between alignment handling between TextNode2D and CanvasText (CGI1-34241 - 10093). 
 CanvasText rendering changes parts of the scene tree which triggered a continuous layout invalidation. This has been fixed (CGI1-35915). 
 Improvements have been done on unloading CanvasText (CGI1-35925). 
 Blending text with RGBA bitmap renderer has been changed (CGI1-29181 - 9946). 
 Outline in texture was not cleared correctly in all cases. This has been fixed (CGI1-36032 - 10119). 
 Reworks have been done on the way truncation is handled by TextNode2D and CanvasText (CGI1-38325). 
 The HarfBuzz font cache led to position issues when two equal characters with different font sizes have been rendered consecutively. This has been fixed (CGI1-37985 - 10149). 
 Improved building with Monotype under integrity systems. Interpretation of datatypes is platform dependent. The improvement matches Monotypes requirements in most use cases (CGI1-39895). 
 A negative bearing in glyph data lead to render fragments outside of the boundaries. Text has been moved inside the boundaries in case a size has been set. (CGI1-38325) 
 
 
 
 This might lead to a pixel movement in some cases by the value of negative bearing.
