Wp-calypso: Focused Launch: avoid using @wordpress/core in package hooks in order to get/set site title

[ciampo]

Currently the useDomainSearch() and useTitle() hooks get/set the site title by accessing core functions. In particular:

• https://github.com/Automattic/wp-calypso/blob/204b43c25d3064be47e48edc0fa066c59a29711a/packages/launch/src/hooks/use-domain-search.ts#L18
• https://github.com/Automattic/wp-calypso/blob/204b43c25d3064be47e48edc0fa066c59a29711a/packages/launch/src/hooks/use-title.ts#L17
• https://github.com/Automattic/wp-calypso/blob/204b43c25d3064be47e48edc0fa066c59a29711a/packages/launch/src/hooks/use-title.ts#L23-L24

The new hooks introduced in https://github.com/Automattic/wp-calypso/pull/46881 should be used instead.
