ProjectExplorer: Use Core::Id as RunMode "enum values"

This provides a way for third-party plugins to implement run
modes without the need to add a value to the central enum or
using manual workarounds like RunMode(*(int*)&someUniqueObject).

Instead of centrally defined enum values this uses Core::Id that could
be defined anywhere.
