Replace intc, bytec instructions with int and byte instructions

Teal allows declaring constants using `intcblock` which can be accessed later using `intc {constant number}` instruction. When detectors traverse the contract, they don't have access to integer value the `intc` refers to. This may result in False Positives as detectors can't reason about the values declared using `intc`. Same goes for `bytecblock` and `bytec` instructions.

The issue does not name files or tests. Start by locating the Teal instruction handling and detector traversal for intcblock/intc and bytecblock/bytec. Done means detectors can reason about the referenced integer and byte values without the false positives described.
