feat: add crate sdk-prover, and add functionality to get self_prog_id within

[codeblooded1729]

The PR introduces the crate sdk-prover. The need for this crate arose from native programs requiring access to the self_prog_id of their guest programs. sdk was insufficient in this regard, since it was hard to have it depend on circuits and runner (since they themselves depend on sdk). Also, a need for a version of sdk was felt, which would have access to proving system (in the case of self_prog_id, we need to have a dry run of Program, and tools to compute merkle caps of certain tables). Hence the crate, and its first module, prog_id_bytes.
Since an impl of Programidentifier, which creates self_prog_id out of its ELF, would create a cyclic dependency, we implement the above for a similar struct ProgId inside sdk-prover instead, and further implement trait From<ProgId> for ProgramIdentifier. Now, a native program, for say token example, can get ProgramIdentifier of its guest program by the following line of code

let token_program: ProgramIdentifier = ProgId::from_elf(&format!("{}{}", ELF_DIR, "tokenbin")).unwrap().into();

This PR also introduces a new CLI command self-prog-id which dumps the the same for given ELF. We also update the example_prog_id for core examples, with their correct version.
First part of tracking issue #1703

We need to build the ELF first, since we require their ProgramIdenitifier in native execution.
