deps: patch V8 to run on older XCode versions

ryzokuken · MylesBorins · commit eac35c606180 · 2020-07-16T17:09:15.000-04:00
Patch V8 (compiler/js-heap-broker.cc) to remove the use of an optional property, which is a fairly new C++ feature, since that requires a newer XCode version than the minimum requirement in BUILDING.md and thus breaks CI.
