ci: cross python wheel

[xslingcn]

We can build a single python wheel for all supported python versions.

• Remove the python versions matrix
• Add --py-limited-api config in building commands

[xslingcn]

Can't test it now because the self-hosted runner is not set up in github actions at the moment.

flashinfer/.github/workflows/release_wheel.yml

Lines 37 to 41 in 56f8eca

	runs-on: [self-hosted]
	steps:
	- uses: actions/checkout@v4
	with:
	submodules: true

Hi @youkaichao @comaniac , we are using --py-limited-api to build wheels for more python versions, do you think we did it correctly?

The usage of Limited API is not very well documented for setuptools, but I've found some references:
pypa/packaging.python.org#1376
pytorch/pytorch#138088

[youkaichao]

Looks reasonable. can you test it?

Let's first check whether this works on nightly wheels.
