* feat: add support for generating tipset CIDs
(cherry-picked from feat/nv18-fevm)
* feat: fvm: add support for looking up past tipset CIDs
We do this by adding yet another "getter" to the VM that resolves an
epoch into a TipSetKey.

This also ignores the VM "Flush" option and instead, flushes
unconditionally (in the FVM):
1. In the FVM, we don't read blocks on flush (ever).
2. All _uses_ of TVX use a "proxy" blockstore that buffers writes, so
nothing should actually get flushed to lotus.
1. Include the builtin-actors in the lotus source tree.
2. Embed the bundle on build instead of downloading at runtime.
3. Avoid reading the bundle whenever possible by including bundle
metadata (the bundle CID, the actor CIDs, etc.).
4. Remove everything related to dependency injection.
1. We're no longer downloading the bundle, so doing anything ahead
of time doesn't really help.
2. We register the manifests on init because, unfortunately, they're
global.
3. We explicitly load the current actors bundle in the genesis
state-tree method.
4. For testing, we just change the in-use bundle with a bit of a
hack. It's not great, but using dependency injection doesn't make
any sense either because, again, the manifest information is
global.
5. Remove the bundle.toml file. Bundles may be overridden by
specifying an override path in the parameters file, or an
environment variable.

The next FVM version will only support nv15+.
This change also disables the FVM before nv15, even if enabled through
the environment variable. This allows "catching up" from before nv15.
