InputText: do not require anymore that CursorPos be clamped by user code. (#9029)

Browse Source 
Add clamping outside of callback code + simplify logic. The previous logic checking for difference was because old code e.g. 21d03edcb0 required a ImTextCountCharsFromUtf8() which is not required since #7925.
