df08301e76 Reformat Python code with yapf. (#2589)
I've add an option to yapf to do what we want for long lines, see
https://github.com/google/yapf/pull/1177.  We can now have a real Python
formatter, yay!

To make this PR, I ran my modified yapf over the repository, then looked
over the full diff.  Where yapf was mangling the param list of long
function decls/calls (mostly kernels), I manually added `#` to put
linebreaks where we want.  I fixed up other formatting too -- mostly
adding or removing a trailing comma from lists.

Overall, trailing `#` was sufficient to get formatting similar to our
current code.  I didn't have to disable yapf anywhere.

b27a91a113 [FRONTEND] Enable triton to support register thirdparty backend at runtime (#1643)
This PR intends to provide a mechanism to support a third-party backend
at runtime to generate the backend-specific code.

The mechanism provided a common class to abstract the third-party
backend logic and two essential functions to register and get the
third-party backend at runtime.

- `BaseBackend`: A common class to abstract the third-party backend
logic
- `register_backend`: Register a third-party backend with a given device
type
- `get_backend`: Get the third-party backend with a given device type

Generally, a third-party backend must inherit from `BaseBackend` and
implement all the member functions according to the backend
characteristics. As long as the backend implementation is ready, the
third-party backend can invoke `register_backend` to register it under a
given device. During the kernel compilation and execution, the mechanism
will get the registered backend to generate the kernel and launcher code
for a given device.

This PR added a dummy backend to simulate a third-party backend and
demonstrate the usage.
