Using AccountId (or Option<AccountId> as the type of a dynamic_params parameter fails parsing

Description of bug

Due to the fact that dynamic_params macro only allows for static items, if you do something like this:

#[dynamic_params(RuntimeParameters, pallet_parameters::Parameters::<Runtime>)]
pub mod dynamic_params {
	use super::*;

	#[dynamic_pallet_params]
	#[codec(index = 0)]
	pub mod inflation {
		#[codec(index = 0)
		pub static Account: AccountId = AccountId::from([0u8; 32]);

		// OR THIS

		#[codec(index = 0)
		pub static MaybeAccount: Option<AccountId> = None;
	}
}

The expansion process will fail, with this error:

error[E0119]: conflicting implementations of trait `From<BurnDestinationValue>` for type `core::option::Option<BurnDestinationValue>`
     --> /Users/pandres95/Documents/Virto/Development/Fellowship/runtimes/relay/kusama/src/lib.rs:692:2

      = note: conflicting implementation in crate `core`:
              - impl<T> From<T> for core::option::Option<T>;
      = note: this error originates in the attribute macro `dynamic_pallet_params` (in Nightly builds, run with -Z macro-backtrace for more info)
