Clear inline mocks at the end of individual Bluetooth tests

When using inline mock maker, clean up inline mocks to prevent
OutOfMemory errors. See https://github.com/mockito/mockito/issues/1614.
See also b/259280359.

Ideally, inline mocks are cleared after each individual test instead of
the test class, but Bluetooth unit tests crashed when attempting to
clear inline mocks in the @After method, so ag/20652385 resorted to
clearing them in an @AfterClass method.

This CL uses Rules instead to clear inline mocks after each individual
test. It takes inspiration from
https://github.com/mockito/mockito/issues/1902, in particular:

"JUnit runs @Before after each rule, and @After before each rule. In
this particular case clearInlineMocks() removed internal handlers of all
inline mocks, but MockitoJUnit rule still needs to use them... The
solution is to wrap clearInlineMocks() in a TestRule as well, and..."
and enforce the ordering.

Test: atest CarServiceUnitTest -- --exclude-filter \
'"CarServiceUnitTest com.android.car.bluetooth.FastPairProviderTest"'
