LogManager: Unconditionally evaluate assertion conditions

A prevalent pattern in the FEX codebase is to compute some data and store it
in a maybe_unused variable that's only ever passed to LOGMAN_THROW_A_FMT.
Besides few exceptions, we never compute expensive data in the macro
arguments themselves, so we can remove a lot of code noise by unconditionally
evaluating the condition even in assertion-disabled builds.
