Bartłomiej Dach c361e6d3c2 Adjust gameplay sample models to support custom sample sets

This is a set of model changes which is supposed to facilitate support
for custom sample sets to the beatmap editor that is on par with stable.

It is the minimal set of changes. Because of this, it can probably be
considered "ugly" or however else you want to put it - but before you
say that, I want to try and pre-empt that criticism by explaining where
the problems lie.

Problem #1: duality in sample models
---

There is currently a weird duality of what a `HitObject`'s samples will
be.

- If an object has just been placed in the editor, and not saved /
  decoded yet, it will use `HitSampleInfo`.

- If an object has already been encoded to the beatmap at least once, it
  will use `ConvertHitObjectParser.LegacyHitSampleInfo`.

As long as that state of affairs remains, `HitSampleInfo` must be able
to represent anything that `LegacyHitSampleInfo` can, if feature parity
is to be achieved.

Problem 2: The 0 & 1 sample banks
---

Custom sample banks of 2 and above are a pretty clean affair. They map to
a suffix on the sample filename, and said samples are allowed to be
looked up from the beatmap skin. `Suffix` already exists in
`HitSampleInfo`.

However, the 1 custom sample bank is evil. It uses *non-suffixed*
samples, *allows lookups from the beatmap skins*, contrary to no bank /
bank 0, which *also* uses non-suffixed samples, but *doesn't* allow them
to be looked up from the beatmap skin.

This is why `HitSampleInfo.UseBeatmapSamples` has been called to
existence - without it there is no way to represent the ability of using
or not using the beatmap skin assets.

As has been stated previously in discussions about this feature, it's
both a *mapping* and a *skinning* concern.

There are many things you could do about either of these problems, but I
am pretty sure tackling either one is going to take *many* more lines of
code than this commit does. Which is why this is the starting point of
negotiation.
