Revert of [regexp] Create property on result for each named capture (patchset #9 id:160001 of https://codereview.chromium.org/2630233003/ )

Reason for revert:
Some heap tests are broken leading to failures on nosnap builds:

https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20arm64%20-%20sim%20-%20nosnap%20-%20debug/builds/3677

Reverting again until tests are fixed to keep bots green.

Original issue's description:
> [regexp] Store named captures on the regexp result
>
> This implements storing named captures on the regexp result object.
> For instance, /(?<a>.)/u.exec("b") will return a result such that:
>
> result.group.a  // "b"
