Removes -Wimplicit-fallthrough=5 from the gcc warnings
-Wimplicit-fallthrough=3 is added by -Wextra, which we already set. Bumping the warning level only changes how fall-through comments are parsed, with level 5 turning off fall-through comments entirely. This is unnecessary and results in having to do extra work to squash warnings when included external code uses fall-through. This change also adds /* FALLTHROUGH */ comments where H5_ATTR_FALLTHROUGH is used so compilers that don't use attributes but do respect fall-through comments don't raise spurious warnings.
