`clang-repl --cuda` was previously crashing with a segmentation fault,
instead of reporting a clean error

The underlying issue was that the `DeviceCompilerInstance` (used for
device-side CUDA compilation) was never initialized with a `Sema`, which
is required before constructing the `IncrementalCUDADeviceParser`.

https://github.com/llvm/llvm-project/blob/89687e6f383b742a3c6542dc673a84d9f82d02de/clang/lib/Interpreter/DeviceOffload.cpp#L32

https://github.com/llvm/llvm-project/blob/89687e6f383b742a3c6542dc673a84d9f82d02de/clang/lib/Interpreter/IncrementalParser.cpp#L31

Unlike the host-side `CompilerInstance` which runs `ExecuteAction`
inside the Interpreter constructor (thereby setting up Sema), the
device-side CI was passed into the parser uninitialized, leading to an
assertion or crash when accessing its internals.

To fix this, I refactored the `Interpreter::create` method to include an
optional `DeviceCI` parameter. If provided, we know we need to take care
of this instance too. Only then do we construct the
`IncrementalCUDADeviceParser`.

Problem :

1) The destructor currently handles no clearance for the DeviceParser
and the DeviceAct. We currently only have this

https://github.com/llvm/llvm-project/blob/976493822443c52a71ed3c67aaca9a555b20c55d/clang/lib/Interpreter/Interpreter.cpp#L416-L419

2) The ownership for DeviceCI currently is present in
IncrementalCudaDeviceParser. But this should be similar to how the
combination for hostCI, hostAction and hostParser are managed by the
Interpreter. As on master the DeviceAct and DeviceParser are managed by
the Interpreter but not DeviceCI. This is problematic because :
IncrementalParser holds a Sema& which points into the DeviceCI. On
master, DeviceCI is destroyed before the base class ~IncrementalParser()
runs, causing Parser::reset() to access a dangling Sema (and as Sema
holds a reference to Preprocessor which owns PragmaNamespace) we see
this
```
