Helper to assert that a value does not have any bit set outside of the
mask. To be used with "all bits mask" of enum types that enumerate bits.

Not a behavior change, but this allow us to decide what function pointer
to use within this function (instead of forcing callers to decide that).
In the following commits this will be helpful. We'll add more curves
besides 3x1D LUT's and, depending on the curve, the function pointer
signature may differ.
Also, we now pass the xform directly to the function, and it can select
the curves depending if it is being called for a pre or a post curve.

Add yet another flavor of assertion macros.
Unlike libc assert.h assert(), these cannot be easily disabled by the
build. They also print both the implied expression and the compared
values.
Unlike ZUC macros, there is much less framework code and it can handle
also floating-point types.
The function custom_assert_fail_ can be redefined, meaning that
different compilation units can do different things on failure.
Also the 'compositor' parameter was added to the new macros because we
plan to use these asserts in our log infrastructure, and we want to
print the "failure" messages in the right log scopes. Having the
compositor already in the macros will avoid double work.
Another future possibility is to write specific asserts for the test
suite. So we would be able to write a test suite failure function that
just print what "failed" without aborting.
There is also limited support for custom types.
These are actually pretty similar to libinput's litest macros.
