This commit: + Adds support for a protocol which enables inter-op between concrete, tfhe-rs and potentially other contributors to the fhe ecosystem. + Gets rid of hand-made serialization in the compiler, and client/server libs. + Refactors client/server libs to allow more pre/post processing of circuit inputs/outputs. The protocol is supported by a definition in the shape of a capnp file, which defines different types of objects among which: + ProgramInfo object, which is a precise description of a set of fhe circuit coming from the same compilation (understand function type information), and the associated key set. + *Key objects, which represent secret/public keys used to encrypt/execute fhe circuits. + Value object, which represent values that can be transferred between client and server to support calls to fhe circuits. The hand-rolled serialization that was previously used is completely dropped in favor of capnp in the whole codebase. The client/server libs, are refactored to introduce a modular design for pre-post processing. Reading the ProgramInfo file associated with a compilation, the client and server libs assemble a pipeline of transformers (functions) for pre and post processing of values coming in and out of a circuit. This design properly decouples various aspects of the processing, and allows these capabilities to be safely extended. In practice this commit includes the following: + Defines the specification in a concreteprotocol package + Integrate the compilation of this package as a compiler dependency via cmake + Modify the compiler to use the Encodings objects defined in the protocol + Modify the compiler to emit ProgramInfo files as compilation artifact, and gets rid of the bloated ClientParameters. + Introduces a new Common library containing the functionalities shared between the compiler and the client/server libs. + Introduces a functional pre-post processing pipeline to this common library + Modify the client/server libs to support loading ProgramInfo objects, and calling circuits using Value messages. + Drops support of JIT. + Drops support of C-api. + Drops support of Rust bindings.
