The macros defined at bw_fixed are important mathematical definitions,
specifying masks to get the fractional part and the maximum and minimum
values of I64. In order to enable unit tests for bw_fixed, it is
relevant to have access to those macros. This commit moves the macros to
the header file, making it accessible to future unit tests.
