Migrate plutus-ledger-api types and functions into independent module

[SeungheonOh]

UPLC and Plutus Ledger API is independent of each other. UPLC defines the "instruction sets" for the smart contracts while Ledger API defines structure of data provided by nodes to each scripts. Different versions of Ledger API can be "run" on different versions of UPLC scripts.

Separating Ledger API modules, currently embedded inside of Plutarch core codebase, into an independent library will make it easier to maintain and quicker to drop-in different versions of plutus-ledger-api if necessary.

We have to note that different versions of ledger api will provide different builtin functions(need confirmation). Ideally, we define wrapper for these builtins in each plutarch-ledger-api library for each respective versions
