chore: move gin::DeprecatedWrappable to gin_helper (#47958) * 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. * chore: fix lint:cpp Co-authored-by: Robo <hop2deep@gmail.com>
