  [Flang][MIF] Allocation of NON-ALLOCATABLE SAVE coarray (#205847)

The goal of this PR is to add support for allocating NON-allocatable
coarrays that are not in the `Main` program.
All allocations will be performed in a function called
`__mif_save_coarrays_allocate`. If this function exists, then
LLVM::GlobalCtors is created (or modified).
The initialization of the MIF with `mif.init` is moved too in a
GlobalCtors with a priority of 0 to ensure that the initialization takes
place before any MIF allocations.
