refactor(preg): replace Preg::split*() with shim preg_split*()

preg_split2()'s limit was always -1 and its flags were always either 0 or
PREG_SPLIT_DELIM_CAPTURE alone, so both arguments are gone: the shim now
exposes preg_split() and preg_split_delim_capture() over a shared
preg_split_impl(). That leaves Preg::split()/split4() as bare
pass-throughs, so callers use the shim functions directly and the wrappers
are dropped along with the now-unreferenced PREG_SPLIT_* constants.
