Add emission of sancov file when CoverageRecord is destroyed. This
will occur when a fuzzer driver exits cleanly, i.e. -runs=0 with an
existing corpus.
Test: make trusty_gatekeeper_fuzzer
Test: adb shell ./trusty_gatekeeper_fuzzer -runs=0 corpus

Trusty shared memory now uses dmabuf instead of memfd. Switch the
coverage buffer allocation to use libdmabufheap.

We want to add coverage statistics to the trusty-ut-ctrl tool, which is
a vendor binary. Thus we need a vendor variant of libtrusty_coverage.
Merges system libtrusty_test and vendor libtrusty into a single
vendor_available library so that we can add vendor_available to
libtrusty_coverage and make it accessible from vendor tools.

Adds the ability to retrieve and save program counter information from
the trusty coverage record data. PC information is saved to a .sancov
file, parseable by the LLVM sancov tool. Sancov can then symbolize and
display this coverage information for consumption by humans.
Adds a sancov dump to the libtrusty_coverage_test for testing.

Test: atest libtrusty_coverage_test
Test: Retrieve sancov file and manually symbolize with sancov
