refactor(ivy): drop element prefixes for all styling-related instructions (#30318)

This is the final patch to migrate the Angular styling code to have a
smaller instruction set in preparation for the runtime refactor. All
styling-related instructions now work both in template and hostBindings
functions and do not use `element` as a prefix for their names:

BEFORE:
  elementStyling()
  elementStyleProp()
  elementClassProp()
  elementStyleMap()
  elementClassMap()
  elementStylingApply()

AFTER:
  styling()
  styleProp()
  classProp()
  styleMap()
  classMap()
  stylingApply()
