Core processor weights/costs refactoring

[grishasobol]

Hi team! I think our weights config in core-processor looks too overloaded:

gear/core-processor/src/configs.rs

Lines 178 to 225 in 80fffbc

	pub struct BlockConfig {
	/// Block info.
	pub block_info: BlockInfo,
	/// Performance multiplier.
	pub performance_multiplier: gsys::Percent,
	/// Max allowed page numbers for wasm program.
	pub max_pages: WasmPage,
	/// Allocations config.
	pub page_costs: PageCosts,
	/// Existential deposit.
	pub existential_deposit: u128,
	/// Outgoing limit.
	pub outgoing_limit: u32,
	/// Outgoing bytes limit.
	pub outgoing_bytes_limit: u32,
	/// Host function weights.
	pub host_fn_weights: HostFnWeights,
	/// Forbidden functions.
	pub forbidden_funcs: BTreeSet<SyscallName>,
	/// Mailbox threshold.
	pub mailbox_threshold: u64,
	/// Cost for single block waitlist holding.
	pub waitlist_cost: u64,
	/// Cost of holding a message in dispatch stash.
	pub dispatch_hold_cost: u64,
	/// Reserve for parameter of scheduling.
	pub reserve_for: u32,
	/// Cost for reservation holding.
	pub reservation: u64,
	/// One-time db-read cost.
	pub read_cost: u64,
	/// One-time db-write cost.
	pub write_cost: u64,
	/// Per written byte cost.
	pub write_per_byte_cost: u64,
	/// Per loaded byte cost.
	pub read_per_byte_cost: u64,
	/// WASM module instantiation byte cost.
	pub module_instantiation_byte_cost: u64,
	/// Amount of reservations can exist for 1 program.
	pub max_reservations: u64,
	/// WASM code instrumentation base cost.
	pub code_instrumentation_cost: u64,
	/// WASM code instrumentation per-byte cost.
	pub code_instrumentation_byte_cost: u64,
	/// Gas multiplier.
	pub gas_multiplier: gsys::GasMultiplier,
	}

My proposal is to make one field for all costs in BlockConfig, ExecutionSettings and ProcessorContext.
For BlockConfig we can make like this:

pub struct BlockConfig {
     pub costs: ProcessCosts,
     ...
}

/// All costs which we use in process_queue and for execution
pub struct ProcessCosts {
      pub execution: ExecutionCosts,
      pub pages: LazyPageCosts,
      // Other for pre-charge
      pub static_page: u64,
      pub storage_read: u64,
      pub storage_write: u64,
      ...
}

/// All costs which we use during contract execution in syscalls
pub struct ExecutionCosts {
     /// syscall calling costs
     pub alloc: u64,
     ...
     /// fees
     pub append_to_waitlist: u64,
     ...
     /// grow cost
     pub memory_grow: u64,
}

Corresponding changes in ExecutionSettings and ProcessorContext

Also for the limits can be done similar refactoring
