This PR enables the module system, in cooperation with the linker, to separate meta and non-meta code in native binaries. In particular, this ensures tactics merely used in proofs do not make it into the final binary. A simple example using `meta import Lean` has its binary size reduced from 130MB to 1.7MB. # Breaking change `importModules (loadExts := true)` must now be preceded by `enableInitializersExecution`. This was always the case for correct importing but is now enforced and checked eagerly.
