### What Replace cargo-deny `skip-tree` with explicit `skip`s for each dependency we wish to allow duplicates. ### Why The `skip-tree` obfuscates the dependencies that we're allowing to be duplicated, and even seems to hide some dependencies being duplicated that don't seem to be part of the soroban-wasmi dependency graph that we depend. This may be due to a bug, or possibly the dep is in the dev dependencies of soroban-wasmi, or some feature that we don't use. I became aware of this issue because I noticed that in #1456 the Cargo.lock file gained a duplicate dependency on the `syn` crate, having already a dependency on version `2.0.39` and gaining a dependency on version `1.0.109`. This is fine and not a problem in and of itself – we can't eradicate all duplicates – except that the `deny.toml` file gained no new entry, no statement to say that we were okay with this new duplicate. In my own testing locally it appears that when the `skip-tree` entry containing `soroban-wasmi` is present, the `syn` duplicate dependency is hidden/silenced, even though it was not a dependency prior to the change that did not involve the `soroban-wasmi` crate. The `skip-tree` config obfuscates the duplicate dependencies in a couple ways. Firstly due to the odd behaviour detailed above we appear to not get notified of new duplicate dependencies, even if they do not appear to be an active in use dependency in our existing graph. Secondly because the `skip-tree` communicates only partially about what is being allowed. In our case the `skip-tree` allows two versions of the `hashbrown` dep, but we actually need the two versions for reasons other than `soroban-wasmi`, so it doesn't tell the full story. Listing out the duplicate dependencies one-by-one is explicit, and it helps us at a glance know what our dupes are, and how many we have, as a signal to "how bad it is getting". ### Known limitations N/A

What
This PR adds support for BLS12-381 in Soroban, by adding host functions for the field and curve operations, new metering cost types, and their calibration.
Why
Please refer to the CAP for motivation and design rationale.
Known limitations
The unit tests currently covers the low-level operations: G1/G2 operations, hashing to curve, pairing.
More test coverage will be added before the PR merged, at the integration level such as BLS signature and the Ethereum test vectors.
