Add infrastructure for precompiled smartcontracts (#927)

* Utils for writing precompiled contracts

* Precompiled contracts in config, override gas_usage for them

* Add base class for precompiled contracts

* Improve utils for precompiled smc

* Implement GETPRECOMPILEDGAS

* Enable precompiles by flag

* Process null data in PrecompiledSmartContract

* Fix ton_block wasm build

* Fix vm::util::store_(u)long

* `GETFORWARDFEE` (`cells bits is_mc - price`) - calculates forward fee.
* `GETPRECOMPILEDGAS` (`- null`) - reserved, currently returns `null`.

* `GETFORWARDFEESIMPLE` (`cells bits is_mc - price`) - same as `GETFORWARDFEE`, but without lump price (just `(bits*bit_price + cells*cell_price) / 2^16`).
