Revert of [regexp] Create property on result for each named capture

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.
