feat: include proxy ABIs in contract-type ABIs

[antazoey]

What I did

fixes: #1249

I could no longer call masterCopy() in a safe proxy since #2400
I not 100% sure why but this PR fixes it.
I think before, it was never actually recognized as a safe proxy...

Anyway, the masterCopy() ABI is sort of hidden.
And proxy ABIs in general (that were not hidden) were not included in the contract-types ABIs you could call.
This PR makes both of those things work.

How I did it

1. When detecting proxies, allow a place for ABIs to be included (not in the cache but just in the API). This helps masterCopy() be included.
2. When looking up a contract-type, also check to see if there is proxy info. If there is, it includes some of the ABIs if it is not already there. This way, past cached contract types (safes) will also suddenly work when calling .masterCopy().
3. Also when caching a deployment, such as local testing environment using Safe (ape-safe's tests), include the ABIs so the returned instance can use masterCopy()

Can get ape-safe tests to pass again, altho this all started because was debuggin a different problem...

Show it Working

In [7]: contract = Contract("0x4Fabb145d64652a948d72533023f6E7A623C7C53")

In [8]: contract.implementation
Out[8]: implementation() -> address


In [9]: contract.balanceOf
Out[9]: balanceOf(address _addr) -> uint256

Example of Safe!

First, delete any cached contract. This also deletes the proxy info that is cached, you can check!

In [1]: del chain.contracts['0x872Df5f6CF2C2Eaa9e7511AB079D263AB8fdc79f']

Next, get this contract as if it is the first time! Notice it uses Etherscan...

In [2]: contract = Contract("0x872Df5f6CF2C2Eaa9e7511AB079D263AB8fdc79f")
contract.

Show you can call both proxy ABIs as well as the actual safe ABIs:

In [3]: contract.masterCopy()
Out[3]: '0xfb1bffC9d739B8D520DaF37dF666da4C687191EA'

In [4]: contract.setGuard
Out[4]: setGuard(address guard)
