Nav: refactor SetKeyboardFocusHere() into using Nav facility. Fix it for clipped items. (#343, #4079, #2352, #432)

Browse Source 
+ Removed references to counter used by previous implementation of SetKeyboardFocus functions (the TabStop ones will be removed after)

@ -57,6 +57,13 @@ Other Changes:
- TextUnformatted: Accept null ranges including (NULL,NULL) without asserting, in order to conform
to common idioms (e.g. passing .data(), .data() + .size() from a null string). (#3615)
- Disabled: Added assert guard for mismatching BeginDisabled()/EndDisabled() blocks. (#211)
- Nav: Fixed using SetKeyboardFocusHere() on non-visible/clipped items. It now works and will scroll
toward the item. When called during a frame where the parent window is appearing, scrolling will
aim to center the item in the window. When calling during a frame where the parent window is already
visible, scrolling will aim to scroll as little as possible to make the item visible. We will later
expose scroll functions and flags in public API to select those behaviors. (#343, #4079, #2352)
- Nav: Fixed using SetKeyboardFocusHere() from activating a different item on the next frame if
submitted items have changed during that frame. (#432)
- Nav: Fixed toggling menu layer with Alt or exiting menu layer with Esc not moving mouse when
the NavEnableSetMousePos config flag is set.
- Nav: Fixed a few widgets from not setting reference keyboard/gamepad navigation ID when
