Jack Grigg 7ea240dbdf book: Rewrite `MerkleCRH` gadget page 
The page now follows the pattern of other chip-specifying pages in how
it documents constraints (in particular, giving the specific form of the
constraint to match the implemented AST).

Additionally, a typo in the decomposition constraint for `left` has been
fixed (the implementation was correct).

halo2_proofs: rename variables for consistency 
This changes variable names in the multiopen and commitment opening implementations
and the book's protocol description to keep names and indicies consistent with one
another.

Daira Hopwood c4bdab59e3 Improve the explanation of incomplete addition: 
* use biimplication in the correctness argument to ensure both soundness and completeness;
* avoid introducing lambda at all; it's unnecessary and omitting it shortens the explanation.

Jack Grigg a2367abcaf Migrate to `halo2_gadgets` crate in subdir 
- The crate module structure from `orchard` has been flattened.
- The book pages we want to include in `halo2` have been moved to their
  target location, to avoid any conflicts during the merge.
- Common files that already exist in zcash/halo2 have been removed.

The tests do not compile as of this commit, due to Orchard-specific
