f16ef601d4 memtag_test: improve capturing of test results 
Using debuggerd + logcat parsing is unreliable and slow, print SEGV signal code to stderr instead.

155800526a memtag_test: improve tag_distinctness test 
- check that tag distinctess checks are actually reached (it was previously verified manually by
looking at the now-removed printf output)
- check that only non-reserved tags are used
- check that all of non-reserved tags are used
- print tag usage statistics at the end of run

28d5d394cf memtag_test: remove usages of rand() 
It didn't work correctly due to not being seeded and its usage wasn't necessary.

576328b1b4 android: add MTE tests 
To run them, connect an MTE-enabled device via adb and execute `atest HMallocTest:MemtagTest`.

Since these tests are not deterministic (and neither is hardened_malloc itself), it's better to run
them multiple times, e.g. `atest --iterations 30 HMallocTest:MemtagTest`.

There are also CTS tests that are useful for checking correctness of the Android integration:
`atest CtsTaggingHostTestCases`
