OmitDeep: Fix removal of multiple paths within arrays

[som-sm]

Fixes #959 (comment)

Just enabling recurseIntoArrays for SharedUnionDeep within OmitDeep fixes the above issue, however, it causes some existing test cases to fail, as SharedUnionDeep currently fails when instantiated with arrays where the non-fixed part precedes the fixed part (will open an issue for this).

import { SharedUnionFieldsDeep } from "type-fest";

type Test = SharedUnionFieldsDeep<{a: [...{a: 1}[], {b: 1}]}, {recurseIntoArrays: true}>
//   ^? type Test = { a: {}[]; }

So, this PR removes usage of SharedUnionDeep from OmitDeep and replaces it with logic similar to what is used in SetRequiredDeep.
