[Do Not Merge] Revert "Implement a global maximum on number of shortcuts an app can publish"

This reverts commit ff75f06d8a5e712b00e59ab1892162a61fa1e988.

Reason for revert: bugs related to conversation shortcuts can lead to system retaining shortcuts exceeding this number, causing crashes in chat apps such as whatsapp, messages ... e.t.c
