[Housekeeping] [flytekit] Investigate better handling of incorrect dataclass/enum types

[wild-endeavor]

Describe the issue

Issue originally reported in https://flyte-org.slack.com/archives/C01P3B761A6/p1647360364170899

from dataclasses import dataclass
from dataclasses_json import dataclass_json
from enum import Enum

from flytekit import task, workflow

# ERROR: having these two annotations causes
# TypeError: __call__() missing 1 required positional argument: 'value'
@dataclass_json
@dataclass
class Aggregation(Enum):
    GROUP_1x1 = "1x1"
    GROUP_5x1 = "5x1"

@dataclass_json
@dataclass
class Nested:
    agg: Aggregation

@task
def tsk(nested: Nested):
    if nested.agg == Aggregation.GROUP_1x1:
        print("1x1")
    elif nested.agg == Aggregation.GROUP_5x1:
        print("5x1")
    else:
        raise ValueError("bad aggregation value")

@workflow
def wf():
    a = tsk(nested=Nested(agg=Aggregation.GROUP_1x1))

if __name__ == "__main__":
    wf()

The combination of dataclass and Enum (which shouldn't be done) causes errors that are hard to understand. Investigate whether flytekit can report this error any better.
