Update build process

[Erotemic]

This PR is for the 3.5.2 patch release, which shouldn't have any impact on the functionality of the library. I'm simply upgrading the build and CI infrastructure to match templated patterns I'm defining in "xcookie" (which is still fairly hard coded and not ready for general consumption, but using it on this repo will help remove some of that boilerplate).

This is motivated by preparing builds for the 3.11 release. While I'm messing with the internals, I may add a readthedocs page and doctests.

Seems like there is an issue with the C-API in 3.11

        /project/_skbuild/linux-x86_64-3.11/cmake-build/line_profiler/_line_profiler.c: In function ‘__pyx_f_13line_profiler_14_line_profiler_python_trace_callback’:

Will have to dig in more to update to be compatible.

This 3.11 issue looks like it might be involved, or at least it goes beyond my immediate expertise. I'm going to open an issue and hope that someone can help here.
