libpayload: Remove default empty implementations in mock cache.h

The mock/arch/cache.h file exists for libpayload unit tests. However,
the default implementations (as empty macros) in it make these functions
difficult to mock in unit tests.

Therefore, we follow what's done for mock/arch/io.h, by only including
function declarations in the header. Each test is expected to implement
mocks for these cache functions when required.
