CU-86dt50abt - Error when compiling using union type notation with | (bitwise or) in Event argument type

[meevee98]

Summary or solution description
Fixed the behavior of typeA | typeB to have the same behavior as Union[typeA, typeB] on Event definitions.

How to Reproduce

neo3-boa/boa3_test/test_sc/event_test/EventNep17TransferBuilt.py

Lines 4 to 11 in 446f3ad

	transfer = CreateNewEvent(
	[
	('from', UInt160 | None),
	('to', UInt160 | None),
	('amount', int)
	],
	'Transfer'
	)
