Upstreams further parts of `do concurrent` to OpenMP conversion pass
from AMD's fork. This PR extends the pass by adding support for mapping
to the device.

Avoid using extends, and adding the high and low half and use
extadd_pairwise instead.

This PR deletes the `createLowerGpuOpsToROCDLOpsPass` constructor from
the .td file, making the `createConvertGpuOpsToROCDLOps` pass available
to users. This has the following effects:

1. `createLowerGpuOpsToROCDLOpsPass` is not available anymore. Instead,
`createConvertGpuOpsToROCDLOps` should be used. This makes the interface
consistent with ConvertGpuOpsToNVVMOps.

2. To call `createConvertGpuOpsToROCDLOps`, the options must be passed
via ConvertGpuOpsToROCDLOpsOptions. This has the side effect of
making the `allowed-dialects` option available, which was not accessible
via C++ before.

Fixes regression casued by #156817.

In relation to the approval and merge of the
https://github.com/llvm/llvm-project/pull/76088 specification about
multi-image features in Flang.
Here is a PR on adding support of the collectives CO_BROADCAST, CO_SUM,
CO_MIN and CO_MAX in conformance with the PRIF specification.

These instructions have a eqz/nez operand like Zicond and
XVentanaCondOps so the goal of using bexti seems applicable to them as
well.
