CI changes

Fixing existing runs:

• Don't run Jedi on PyPy. (see https://github.com/python-trio/trio/pull/2887 and https://github.com/python-trio/trio/pull/3075) (need to update test_static_tool_sees_class_members too)
• Only run autodeps in python-trio/trio (see https://github.com/python-trio/trio/pull/2892)
• Add a gc.collect() to the top of test_for_leaking_fds (this seems to address test flakiness I've seen elsewhere) (see https://github.com/python-trio/trio/pull/2888)
• Start running mypy on PyPy. (see https://github.com/python-trio/trio/pull/3075)
• switch macos to run on m1 (see https://github.com/python-trio/trio/pull/2953)

Adding more runs:

• Add an anaconda run
• Alpine run (see https://github.com/python-trio/trio/pull/2933)
• Try out qemu for a freebsd
• Cython run (see https://github.com/python-trio/trio/pull/2942)
  • Run full test suite on Cython
• Update MacOS and Windows Python matrix to support 3.11 and 3.12. (see https://github.com/python-trio/trio/pull/3017)
• Add CPython 3.13 (see https://github.com/python-trio/trio/pull/3005)
• ... Android run??? (https://github.com/marketplace/actions/android-emulator-runner ??)
• pypy nightly 3.11 (not possible)
• add pypy runs for macos (see https://github.com/python-trio/trio/pull/3074)
• add pypy runs for windows (see #2776 and #2678) (see https://github.com/python-trio/trio/pull/3074)

Removing runs:

• Don't run PyPy nightlies less than 3.11 (see https://github.com/python-trio/trio/pull/2952)

These feel like they will take more motivation than I currently have :(

Review the repository's CI workflow configuration and the unchecked items in the issue, especially the Anaconda run, QEMU-based FreeBSD run, full Cython test suite, and possible Android run. Use the existing CI changes and linked pull requests as context; done means the selected runs are configured and the intended test coverage executes successfully.
