refactor(pcre): drop the two bespoke isMatch variants

is_match_named and is_match_with_indexed_captures reshaped a match into
a name-keyed map or a number-positioned vec, each allocating a String
per group up front for callers that then read one or two of them. Every
one of the eleven call sites ports a plain Preg::isMatch in PHP, so they
now call is_match3 and reach for the group they want through
get(&CaptureKey::ByIndex(N)) / get(&CaptureKey::ByName(..)), the same
way the rest of the tree already reads a match.

Falling out of that: PregNamedGroups existed only to type the first
variant; PregMatches::iter() only to build both; and PregMatches::pattern
only to give iter() the capture names. PregMatches is now a plain
wrapper over regex::Captures, so preg_replace_callback no longer clones
the resolved pattern for every match, and preg_match_map! is internal to
the shim again.

SvnDriver::get_file_content and get_change_date recover the flat
`isMatch(..) && $match[2] !== null` condition the PHP has, which the vec
shape had forced into a nested if.
