Backport try_megabytes_to_bytes from EE

EE adds this method to Gitlab::Utils, which is also required by our
SimpleCov helper. This prevents us from injecting EE modules into
Gitlab::Utils, because the necessary bits for this are not yet in place.

To work around this we just backport try_megabytes_to_bytes, as there's
no particular reason to keep this in EE only.
