feat: mark 4 amendments as obsolete: (#4291)

Browse Source 
Add the ability to mark amendments as obsolete. There are some known
amendments that should not be voted for because they are broken (or
similar reasons).

This commit marks four amendments as obsolete:

1. `CryptoConditionsSuite`
2. `NonFungibleTokensV1`
3. `fixNFTokenDirV1`
4. `fixNFTokenNegOffer`

When an amendment is `Obsolete`, voting for the amendment is prevented.
A determined operator can still vote for the amendment by changing the
source, and doing so does not break any protocol rules.

The "feature" command now does not modify the vote for obsolete
amendments.

Before this change, there were two options for an amendment's
`DefaultVote` behavior: yes and no.

After this change, there are three options for an amendment's
`VoteBehavior`: DefaultYes, DefaultNo, and Obsolete.

To be clear, if an obsolete amendment were to (somehow) be activated by
consensus, the server still has the code to process transactions
according to that amendment, and would not be amendment blocked. It
would function the same as if it had been voting "no" on the amendment.

Resolves #4014.

Incorporates review feedback from @scottschurr.
