Support automatic optimizer builds of different feature flags

[NoahSaso]

This configures the workspace optimizer to automatically generate different versions of contracts for each of the different feature flags we use to support different chain environments.

Specifically:

cw-tokenfactory-issuer needs to support:

• osmosis tokenfactory
• cosmwasm tokenfactory
• kujira tokenfactory

cw-vesting needs to support:

• chains with x/staking
• chains without x/staking

huge thank you to @CyberHoward in CosmWasm/optimizer#148 for adding support for this 🙏🙏
