Summary [css-nesting] Save memory when we only need old-school StyleRule (=non nested)

Support for CSS Nesting adds 2 members to the StyleRule class (the resolved selector list, and the list of children rules). This creates a regression in Membuster benchmark (~2Mb). We should have a "happy path" where we don't pay the memory cost of the nesting feature when we don't need it.
