Jack Grigg 3486703bd2 halo2_gadgets: Refactor fixed-base scalar mul gadget APIs 
The new `EccInstructions` instructions, and the corresponding changes to
existing instructions, enable chips to choose when to witness or constrain
the scalars, and simplify scalar reuse (though reuse is not implemented
for `EccChip` yet).

`FixedPoint::mul` and `FixedPointShort::mul` now has the same API style
as `NonIdentityPoint::mul`.

Jack Grigg 9a12beee73 halo2_gadgets: Rename `halo2` to `halo2_proofs` 
The previous commit renamed `halo2_proofs` back to `halo2` temporarily
to keep the commit size down. This commit performs the rename in a
single pass.

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.
