FEXCore: Switch constant emission to default to NoPad

Most constants don't need to be padded for relocations. So now that
these have all been audited, switch to defaulting to NoPad to reduce
verbosity.

The number of constant that need to be explicitly padded are now marked
and with all the prior changes, this allows bisecting if something has
gone wrong.
