* chore: move gin::DeprecatedWrappable to gin_helper
This is in preparation for migrating to gin::Wrappable
based on cppgc #47922
The upstream class will be deleted soon via roller PR but
the cppgc migration should happen outside the roll, this
change retains the current functionality by copying the
implementation into //electron/shell/common/gin_helper.
The class can be deleted once the cppgc migration is complete.
