test: Add new test framework tools

Add new before/after test functions to be used for clean-up and
tear-down of tests.
Add new asserting functions:
- TEST_EQ ensures that two values are equal
- TEST_NE ensures that two values are not equal
- TEST_BITS_SET ensures that a value contains all bits in mask
- TEST_BITS_CLEARED ensures that a value doesn't contain any
bits in mask

The benefit of these is that unlike TEST_ASSERT they will
also print the values when the assersion is wrong.
