EIP-7916: ProgressiveList and tests

[michaelsproul]

Proposed Changes

Run the EF tests for new types from EIP-7916 and EIP-8016:

• ProgressiveList
• ProgressiveBitList
• Progressive containers
• Compatible unions (requires ssz_derive additions which are written but not tested)

The SSZ generic tests are passing if you run them without compiling the rest of Lighthouse:

cargo test -p ef_tests --release --features ef_tests -- ssz_generic

Everything else is probably broken.

Additional Info

Depends on:

• Progressive list milhouse#82
• ProgressiveBitList and compatible union support ethereum_ssz#67
• ProgressiveMerkleHasher and progressive container support tree_hash#43

Known Issues

• The introduction of BitList<Progressive>::with_capacity has created some type inference ambiguities causing state_processing not to compile. We should probably rename this method in ethereum_ssz.
• Haven't merged unstable since the types refactor nor the gloas-containers merge.

I've made a bunch of progress on this, but it requires local checkouts of ethereum_ssz and tree_hash at the moment. These branches:

• ProgressiveBitList and compatible union support ethereum_ssz#67
• ProgressiveMerkleHasher and progressive container support tree_hash#43

Progressive bitlist tests are currently not passing, need to dig into why. The derive macro for progressive containers with 1 field works though 😅
