fix: warning updating movement flags while rooted (#1858)

Browse Source 
fixes https://github.com/mod-playerbots/mod-playerbots/issues/1854
-----
Also includes fixes for:
-----
* Bots swimming with waterWalk kept switching between swimming and
walking, as result jittering effect swimming under water when water
walking active
* Bots flying close above water they would land on water and start
walking, now they stay flying unless on solid ground they will land and
start walking by design

-----
Moved all flag setting to updateMovementState:
* So all movement flag are handled in updateMovementState which also
contains the restricted movement logic.
* Handle restricted movement logic and preventing SendMovementFlagUpdate
while being restricted.


-----
Known issue when flying the following bots feel a bit jittering, wont
touch for now at least till core movement changes quirks has been dealt
with.

The current code is the extended version of what is originally was
before core merge with refactored movements. Once the core movement
refactors are settled a bit more i would like to revisit this code; as i
would expect more imperative code and less manual flag setting e.g.
bot->SetWaterWalking, SetGravitiy..SetCanFly etc.
