fix(pallet-gear-builtin): calc_gas_info min_limit precharge hint

[ukint-vs]

• Track the largest can_charge_gas check inside the builtin pallet (std-only) and expose it through BuiltinDispatcherFactory.
• Consume the stored hint in calculate_gas_info_impl so RPC estimation keeps the declared gas limit while still reporting the actual burn.
• Add related tests

This should work in wasm as well.

Example fix: if call is in RPC propagate some reserve + unreserve notes, so they will have actual no-op action but modify necessary gas
