Parse and assemble kernel functions (#567) * Parse and assemble kernel functions Written in "EVM++" assembly.

//! Loads each kernel assembly file and concatenates them.
use itertools::Itertools;
Continue work on bootstrapping The kernel is hashed using a Keccak based sponge for now. We could switch to Poseidon later if our kernel grows too large. Note that we use simple zero-padding (pad0*) instead of the standard pad10* rule. It's simpler, and we don't care that the prover can add extra 0s at the end of the code. The program counter can never reach those bytes, and even if it could, they'd be 0 anyway given the EVM's zero-initialization rule. In one CPU row, we can do a whole Keccak hash (via the CTL), absorbing 136 bytes. But we can't actually bootstrap that many bytes of kernel code in one row, because we're also limited by memory bandwidth. Currently we can write 4 bytes of the kernel to memory in one row. So we treat the `keccak_input_limbs` columns as a buffer. We gradually fill up this buffer, 4 bytes (one `u32` word) at a time. Every `136 / 4 = 34` rows, the buffer will be full, so at that point we activate the Keccak CTL to absorb the buffer.

More constants for kernel ASM - `GlobalMetadata` - offsets for global kernel variables in memory - `ContextMetadata` - offsets for context-specific kernel variables in memory - `GAS_CONSTANTS`, based on the yellowpaper Also move constants to a separate module since `aggregator` was getting long.

Have `make_kernel` log the size of each (assembled) file For now it doesn't log filenames, but we can compare against the list of filenames in `combined_kernel`. Current output: ``` [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 0 bytes [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 49 bytes [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 387 bytes [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 27365 bytes [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 0 bytes [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 11 bytes [DEBUG plonky2_evm::cpu::kernel::assembler] Assembled file size: 7 bytes [DEBUG plonky2_evm::cpu::kernel::aggregator::tests] Total kernel size: 27819 bytes ``` This shows that most of our kernel code is from `curve_add.asm`, which makes sense since it invovles a couple uses of the large `inverse` macro. Thankfully that will be replaced at some point.
