Consitently use the new o3tl::convertsToAtLeast/Most(o3tl::roundAway(...), ...)
for all cases in coerce_value that check that a floating-point value falls into
an integer range, even those that don't cause a warning.

The new idlc/test/parser/conversion.tests is deliberately left out of
unoidl/CustomTarget_unoidl-write_test.mk. as unoidl-write doesn't support such
conversions from floating-point to integer types.
