Sumit Kumar Das 3ff8c2dbde esm: avoid super-linear data URL MIME regex ...

The MIME regex used for data: URLs could backtrack super-linearly on a
malformed URL lacking a ',' separator. Make the optional parameter
group anchored on ';' so it cannot overlap with the media-type group.

Adds a benchmark (esm/get-data-protocol-format) parameterized over
path length, so a backtracking regression shows up as an ops/sec
cliff instead of a wall-clock assertion in a test, per review.
