Richard SmithandJon Ross-Perkins ea60e4f491 Track the file kind on SourceLocation rather than computing it from the file name. (#2999) 
This will be more correct if a user file is named prelude.carbon, and
reduces the explorer runtime by about 10% by removing a string
comparison from the check for whether trace output is enabled.

Jon Ross-Perkins 82f33ff384 Use new test framework in explorer to reduce per-test overhead (#2811) 
Isolating test execution time (no build time included):

- Linux, `lit` test-per-file: Elapsed time: 28.214s, Critical Path: 13.97s
- Linux, `cc_test`-per-file: Elapsed time: 11.534s, Critical Path: 6.05s
- Linux, merged `cc_test` with 50 shards: Elapsed time: 11.677s, Critical Path: 11.17s
- Mac, `lit` test-per-file: Elapsed time: 295.686s, Critical Path: 20.00s
- Mac, `cc_test`-per-file: Elapsed time: 55.788s, Critical Path: 3.81s
- Mac, merged `cc_test` with 50 shards: Elapsed time: 16.269s, Critical Path: 7.54s

I'm still leaving a handful of `lit` tests to test end-to-end binary execution. This is why testdata directories are split (`lit` tests next to the `explorer` binary, the `cc_test`s next to `ParseAndExecute`).

Jon Ross-Perkins b828093c87 Start checking for a few possible resource exhaustion scenarios for explorer (#2793) 
I couldn't figure out a way to actually hit a reasonable out-of-memory case once I add the maximum interpreter step count. However, the step count limit seems more important.

I've moved the todo stack limit out of function calls because there are plenty of ways to build up the todo stack without any function calls.

Fixes #2791
