Add automated tests

[gsingh93]

Tests with 12 different kernels on every push/PR. Depends on https://github.com/gsingh93/linux-exploit-dev-env and https://github.com/gsingh93/linux-exploit-dev-env-art-kt.

• arm64 tests are failing because ubuntu-22.04 uses an older version of QEMU
• linux 5.10 tests are failing due to an upstream kernel bug, will be fixed in the next stable kernel release
• android13-5.10 and android14-5.15 tests are failing, and I'm not sure why. Need to investigate more

Tests now use prebuilt qemu-8.2.2 which fixed the arm64 tests. android x86 tests also needed this patch: gsingh93/linux-exploit-dev-env@88a208a

That just leaves the arm64 android13-5.10 that's failing. The default value of SCTLR_EL1 has EPAN enabled when I check it locally, but for some reason it's not set when running this kernel in the Github workflow, so the msr test is failing. Need to debug more to understand why.

Locally I had been testing with android13-5.10. Turns out for some reason, EPAN is not enabled in android13-5.10-lts. After using a different value for SCTLR_EL1 when testing this kernel version, all tests pass (except ones failing due to upstream kernel bugs).
