feat(react-positioning): simplify maxSize options

[YuanboXue-Amber]

Fix item 2 in #28623

Previous Behavior

AutoSize has several options:

export type AutoSize = 'height' | 'height-always' | 'width' | 'width-always' | 'always' | boolean;

export interface PositioningOptions {
  autoSize?: AutoSize;
}

'height' - apply max-height only when floating element overflows boundary.
'height-always' - apply max-height regardless of overflow.
The same goes with true/'always' and 'width'/'width-always'.

There are two examples in issue 28623 2. Consolidate 'height'/'height-always' option, explaining why we need both set of options.

New Behavior

Options 'always'/'height-always'/'width-always' are now obsolete, and equivalent to true/'height'/'width'.

This is achieved by always applying max-height/max-width, but remove them when updatePosition is called.
The size of the content affects the max-height/max-width style we're applying, because the availableWidth/availableHeight from floating ui size middleware is calculated as below:

Test cases are added for both case A and case B mentioned in the above issue.

Additionally, this PR fixes 1.b in #28623 by applying overflow style only when overflow styles aren't present. Therefore user can use inline overflow style to override overflow-x/overflow-y added by maxSize.
