Replace Sapling support-related asserts with JSON errors
This helps prevent users from triggering an assert if they pass in Sapling addresses to RPC calls which do not fully support Sapling yet: z_mergetoaddress, z_importviewingkey and z_exportviewingkey.
Part of #3533.

Fix signing raw transactions with unsynced offline nodes
This PR address the issue in two different ways:
- In `signrawtransaction` we determine the consensus branch ID (which we then later use to construct the transaction) using the chain height. We now also consider the `APPROX_RELEASE_HEIGHT` as this is a better estimation than 0 for the height of the chain if we are unsynced. (This in and of itself solves the Overwinter signing issue).
- We have added an additional parameter to `signrawtransaction` to allow manually overriding the consensus branch ID that zcashd determines we are on. This allows users to work around corner cases where the first strategy is still insufficient.
Closes#3327.
