BLD: Support `x86_64` and `arm64` architectures #17

This PR adds support for multiple architectures, namely:

Introduces hierarchical mechanism for specializing source files for (sub)architectures.
Enables x64_64 arch with haswell, sandybridge, skylakex, and zen subarchs.
Enables arm64 arch with armv8 subarch.
Uses xGEMM_UNROLL_x configs to determine loop unroll size instead of hardcoding them.

CI runs three jobs: ubuntu-latest (which is haswell or zen), macos13 (looks like it's using sandybridge), and macos-latest (an M1 armv8).
