Fix check for whether a trace tag is enabled

With the introduction of libperfetto_tracing, we need to check both
perfetto track_events and atrace categories to determine if a trace
tag is enabled. Perfetto SDK doesn't expose a list (or bitmask) of
all enabled categories, but we can check if a specific category is
enabled.

Rewrote the internal impl for Trace#isTagEnabled to pass the tag into
native and return a boolean instead of getting all the enabled tags
from native and checking in Java.
