[windows][toolchain] Run Swift Runtime execution tests in x86_64 Android emulator

[weliveindetail]

First version for early feedback

[weliveindetail]

I expect to see the same issues with the Android Emulator in CI as in #78762. I will get back to that next week. Results I get locally:

********************
Testing:  0.. 10.. 20.. 30.. 40.. 50.. 60.. 70.. 80.. 90..
********************

Testing Time: 12.00s

8 warning(s) in tests

Nice, any reason you only ran about 34 tests from the compiler validation suite locally? It would be great if the Windows CI ran more of those, alongside the new proposed Android community CI that runs everything but the executable tests on linux, swiftlang/swift-community-hosted-continuous-integration#55, ie those tests that don't require the emulator.

Thanks for your note. This is an early version for a minimal subset of tests. Idea was to get the emulator approach evaluated early, because it would take longer to stabilize in CI. Non-execution tests will follow. This will add a substantial amount of test runtime. I guess we will need to figure out how much of it we run in CI regularly.

Most non-executable tests failed because SWIFT_NATIVE_CLANG/LLVM_TOOLS_PATH wasn't set. Changing that brings us to a pass rate of almost 60%

Total Discovered Tests: 11193
  Unsupported        : 3588 (32.06%)
  Passed             : 6532 (58.36%)
  Expectedly Failed  :   35 (0.31%)
  Failed             : 1035 (9.25%)
  Unexpectedly Passed:    3 (0.03%)

Let's see if we can reproduce this in CI
@swift-ci please test Windows

@swift-ci please test Windows

The build failed for an unrelated reason (flake in LLDB). Enabled AndroidSDK x86_64 now (and disable unrelated tests). Let's try again.

@swift-ci please test Windows

Pass rate on CI machines is much lower:

Total Discovered Tests: 18516
  Unsupported      : 5308 (28.67%)
  Passed           : 2284 (12.34%)
  Expectedly Failed:   30 (0.16%)
  Unresolved       : 6518 (35.20%)
  Failed           : 4376 (23.63%)

I will check the logs and investigate.

Actually, not a good idea to mix these up. I will do the non-executable tests in #79185 and keep this PR focussed on execution tests.
