Performance: Standardize lodash imports to use destructured members (#33040)

Browse Source 
* Performance: Standardize lodash imports to use destructured members
Changes lodash imports of the form `import x from 'lodash/x'` to
`import { x } from 'lodash'` to reduce bundle size.

* Remove unnecessary _ import from Graph component

* Enforce lodash import style

* Fix remaining lodash imports
