Made @rjsf/material-ui only be for Material UI 4 (#2949)

- Deleted the `MuiComponentContext`, `MuiForm5`, `Theme5` and `ThemeCommon` directories (moving the contents of `ThemeCommon/index.js` directly into `Theme`)
- Deleted the `MaterialUIContext` and `MaterialUIContextProps` files and everything in `Theme.tsx` that related to them
- Replaced all fetching of the Material UI components from the `useMuiComponent()` hook with actual imports from `@material-ui/core` and `@material-ui/icons`
- Deleted the `tests/mui-5` directory and fixed up the tests to work with the simple `Form`
- Regenerated the `package-lock.json` file with node-16
- Added the `cs-check`, `cs-format` and `lint` scripts along with `lint-staged` to the `package.json` file
- Copied the `.eslintrc` file from `core`
  - This involved adding `@typescript-eslint`, `eslint` and `eslint-plugin-*`
- Ran `eslint --fix` and `cs-format` over the `src` and `test` directories to fix the build
