Improve all apps loading times.

Updated loadAllApps to load all required icons in a series of bulk sql queries. This reduces the cost of SQL lookups (up to two lookups per user, rather than one lookup per icon)

Bug: 195674813
Test: Added all icons to workspace, added duplicate icons, added icons for same component name from different users
