The allocator index is set from the component genre #157731 . There is
no more need of an operation to set it at a later point.

Some operation creations were updated in flang directory but not all.
Migrate the CUF ops to the new create APIs introduce in #147168

See https://github.com/llvm/llvm-project/pull/147168 for more info.

Switch from `int64_t` to `int64_t*` to fit with the rest of the
implementation.

New tentative with some fix. The previous was reverted some time ago.

Reviewed in #138010

This patch updates several passes to include the DLTI dialect, since
their use of the `fir::support::getOrSetMLIRDataLayout()` utility
function could, in some cases, require this dialect to be loaded in
advance.

Also, the `CUFComputeSharedMemoryOffsetsAndSize` pass has been updated
with a dependency to the GPU dialect, as its invocation to
`cuf::getOrCreateGPUModule()` would result in the same kind of error if
no other operations or attributes from that dialect were present in the
input MLIR module.
