Summary:
Adding some more systrace markers to track load application and the initial bits of MarketplaceHomeApp.
There are a couple big segments worth pointing out with timing from a local `__DEV__: false` run:
* JSBundleRequireTime_end -> BundlePreInitializeCore_start: 360ms
* MobileConfigModuleInit: 210ms
* renderApplication_React_render_start -> MarketplaceHomeAppConstructorSuper_start: 180ms
* MarketplaceHomeAppGetQueryParamsForCachedTopPicks: 100ms
I'm not sure what we can do about any of these except for MarketplaceHomeAppGetQueryParamsForCachedTopPicks where we could break the query params out into a separate file so we don't have to load this 11-thousand-line behemoth just so we can get this snippet:
diffusion/FBS/browse/master/xplat/js/RKJSModules/Apps/Wilde/Marketplace/apps/__generated__/MarketplaceHomeAppQuery.graphql.js$11831-11837
But maybe we have to load it anyway and the query just needs to be optimized (or maybe Relay can optimize the format here).
