This is mainly to help isolate functionality in the hopes of adding a specialised object class for this type of object as suggested by @julealgon in https://github.com/diasurgical/devilutionX/pull/2344#discussion_r667415019
For example, AddSCambBook performs almost the same logic but uses var6 instead of var8 for the trigger condition/identifier.
* Clamp hpPer as a sanity check
* Refactor update mana routines in control.cpp to use PlayerStruct::UpdateManaPercentage
* Remove unnecessary calls to UpdateHP/ManaPercentage
* Unify logic that draws the flasks into a single internal function
* Fix style violations
* Remove unnecessary save/loads of hp/manaPer
The way this variable is used expects a value in this range and it gets clamped again anyway, but this makes the code more similar to the manaPer logic for future refactoring
Identical logic in use, the checks to see if the values are negative can be accomplished using clamp and the same divide by zero guard. I'll combine the two attributes in a near future commit.
control_update_life_mana is called during the game loop before any of the drawing functions so hpPer/manaPer are calculated based on the latest current/max of their respective attributes every frame.
There's no need to do the calculation again in the draw routines. (There's also no need to calculate this every frame but that's going to take a bit to untangle.)
