[mask_rom] Create initial functional tests.

Initial functional tests for mask ROM modules.  These tests utilize
the existing RV32I test infrastructure: they are built as unsigned
code which executes from flash and rely on the primitive boot_rom to
execute them.  The test infrastructure uses the UART DIF to communicate
test results via the UART.

1. Functional test for UART.
2. Functional test for HMAC.

Sample of how to exexute the functional tests.  I plan to automate this
as part of the build-system refactoring.
