Convert aes_test to GTest.
This introduces machinery to start embedding the test data files into
the crypto_test binary. Figuring out every CI's test data story is more
trouble than is worth it. The GTest FileTest runner is considerably
different from the old one:
- It returns void and expects failures to use the GTest EXPECT_* and
ASSERT_* macros, rather than ExpectBytesEqual. This is more monkey
work to convert, but ultimately less work to add new tests. I think
it's also valuable for our FileTest and normal test patterns to align
as much as possible. The line number is emitted via SCOPED_TRACE.
- I've intentionally omitted the Error attribute handling, since that
doesn't work very well with the new callback. This means evp_test.cc
will take a little more work to convert, but this is again to keep our
two test patterns aligned.
- The callback takes a std::function rather than a C-style void pointer.
This means we can go nuts with lambdas. It also places the path first
so clang-format doesn't go nuts.
