This deprecates --vmodule (not available in absl, mapping it to --v for
a very minimal sort of compatibility) and adds the absl::log flags
--minloglevel, --stderrthreshold, --log_backtrace_at, and --log_prefix.

After this it should be possible to build a working `packager` application from the `cmake` branch. Some further logging improvements may be needed to get full parity with the `main` branch in terms of ability to do verbose debug logging, but other than that everything is expected to work.
This removes all chromium dependencies from media/base/ and completes
the build system in CMake.
The ClosureThread class and its classes were removed, as they were
specific to chromium base. ClosureThread has been replaced by
std::thread.
The byte-swapping utilities in network_util.cc have been removed and
replaced with absl.
generate_unique_temp_path() was split out of file_unittest.cc into
file_test_util.cc, where other test suites could make use of it.
WARN_UNUSED_RESULT was replaced with the C++ standard attribute
[[nodiscard]].
The base::Clock interface was replaced with a typedef for a function
pointer that returns the current time.
This re-enables the tests in http_key_fetcher_unittest.cc by using
httpbin.org.
Issue #1047 (CMake porting)

This does not depend on absl, which frees macros.h from any library deps
that would make the CMake dependency tree more complicated. This also
fixes build errors in some environments.
mbedtls works very differently from BoringSSL, and many changes had to
be made in the details of AES decryption to accomodate this.
Beyond the basic changes required for mbedtls, part of the CTS padding
implementation had to be rewritten. I believe this is because of an
assumption that held for BoringSSL, but not for mbedtls. I was unable to
determine what it was, so I rewrote the CTS decryption using reference
materials. After this, tests passed.
The deterministc PRNG I used with mbedtls in the RSA tests differs
somewhat from the old one, so the expected vectors had to be
regenerated. The old determinstic tests were also disabled, and are now
re-enabled.
Since cryptography is sensitive code, and because there were far more
changes needed here than just updating some headers and utility function
calls, this has been split into its own PR for separate review from the
rest of the media/base porting work.
