scripts: twisterlib: coverage: ignore __ASSERT branches

Browse source 
Disable branch coverage for the `__ASSERT` family of macros. Covering
all of the assertion branches by definition means triggering the
assertion, which can be either challenging or impossible to exercise,
and in either case results in the immediate termination of the test.
