Add a new make target called `haiku-line-coverage`

This CL adds a new make target for line coverage, That is, by running
`make haiku-line-coverage` you can get a set of all profile (*.gcno) files
for all fuzz targets and for all critical components of Android,
packed into a zip called `line_coverage_profiles.zip`. Furthermore the set of
all fuzz targets are instrumented with line coverage and packed into
another zip called `line_coverage_fuzz_targets.zip`

To properly run the make target enable NATIVE_LINE_COVERAGE first:
NATIVE_LINE_COVERAGE=true NATIVE_COVERAGE=true COVERAGE_PATHS=* make haiku-line-coverage

Bug: b/148234755
Test: Make target buils successfully on master/aosp. Binaries tested on taimen
devices.
