KSES: Add flex and related long form properties to safe CSS.

Allow `flex`, `flex-grow`, `flex-shrink` and `flex-basis` to be used in inline CSS. As of WordPress 5.3 the block editor is expected to use `flex-basis` inline to set the width in the column block.

Props aduth.
Fixes #47281.
See #37248.
