[anchor-position] Implement auto anchor positioning and auto fallbacks

This patch implements:

1. Evaluation of anchor(auto) and anchor(auto-same) by converting
   auto into the corresponding physical side [1].
2. Generation of automatic anchor fallbacks when one inset contains
   anchor(auto[-same]) and the opposite inset is auto [2]. This is
   done by introducing an OOFCandidateStyleIterator class that
   encapsulates the iteration of all candidate styles for an OOF,
   including the base style, @try fallback styles and automatic
   fallback styles. This class also replaces the existing position
   fallback style enumeration.
