- InputText: internal refactoring to simplify and optimize the code. The ImWchar buffer has been
removed. Simplifications allowed to implement new optimizations for handling very large text buffers
(e.g. in our testing, handling of a 1 MB text buffer is now 3 times faster in VS2022 Debug build).
This is the first step toward more refactorig. (#7925) [@alektron, @ocornut]
