Remove workStore from metadata resolution chain (#90217)
Stacked on #90215
workStore was threaded through 6 functions in resolve-metadata.ts and
the entire createMetadataComponents closure but only used once for
workStore.route in accumulateMetadata. It now reads from
workAsyncStorage.getStore() at that single usage site instead. This
eliminates workStore from the createMetadataComponents parameter list
entirely, bringing it one step closer to being replaceable with plain
components.
