Revert "[COR-2297/] Fix nested offloaded type validation (#552) (#5996)"

[eapolinario]

This reverts commit f20b8aa.

Tracking issue

Related to #5103

Why are the changes needed?

In flyteorg/flytekit#2872 we're handling the case of offloading literals in map tasks single executions explicitly. The impact of this is that we can simplify the handling of this case in the backend, invalidating #5996.

What changes were proposed in this pull request?

Revert #5996.

How was this patch tested?

Confirmed that the original test workflow works:

import logging
from typing import List
from flytekit import map_task, task, workflow,LaunchPlan

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger("flytekit")
logger.setLevel(logging.DEBUG)

@task(cache=True, cache_version="1.1")
def my_30mb_task(i: str) -> str:
    return f"Hello world {i}" * 30 * 100 * 1024

@task(cache=True, cache_version="1.1")
def generate_strs(count: int) -> List[str]:
    return ["a"] * count

@workflow
def my_30mb_wf(mbs: int) -> List[str]:
  strs = generate_strs(count=mbs)
  return map_task(my_30mb_task)(i=strs)

@workflow
def big_inputs_wf(input: List[str]):
   noop()

@task(cache=True, cache_version="1.1")
def noop():
    ...

big_inputs_wf_lp = LaunchPlan.get_or_create(name="big_inputs_wf_lp", workflow=big_inputs_wf)

@workflow
def ref_wf(mbs: int):
  big_inputs_wf_lp(input=my_30mb_wf(mbs))
