rewrite PgpSignEncrypt data flow

- introduce high-level SignEncryptOperation for uri to uri signing/encryption
- use SignEncryptParcel for high-level operation parameters
- use PgpSignEncryptInput plus streams for low-level operation parameters
- get rid of all sign/encrypt logic in KeychainIntentService

/** This parcel stores the input of one or more PgpSignEncrypt operations.

* - Each input uri is individually encrypted/signed
* - If a byte array is supplied, it is treated as an input before uris are processed
* - The number of output uris must match the number of input uris, plus one more
* if there is a byte array present.
* - Once the output uris are empty, there must be exactly one input (uri xor bytes)
* left, which will be returned in a byte array as part of the result parcel.
