deps: patch V8 to run on older XCode versions

ryzokuken · targos · commit c7a0ab4e3d45 · 2021-02-25T00:15:15.000+01:00
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.
