fixed FunctionEncoder for Array in Struct

[SeongUgJung]

What does this PR do?

Pre-condition : array in Struct

struct FooArrayInStruct {
  uint256[] fooIntArray;
  string[] fooStringArray;
  bytes[] fooBytesArray;
}

Action : FunctionEncoder.buildMethodSignature(Function(FooArrayInStruct))

✅ Expected

{method-name}((uint256[],string[],bytes[]))

🟥 Actual

{method-name}((dynamicarray,dynamicarray,dynamicarray))

If array is wrapped in struct, the signature of parameter isn't converted proper type's array but dynamicarray or staticarray.

Where should the reviewer start?

1. Check FooArrayInStruct in AbiV2TestFixture.java
2. Check DynamicStruct.java & StaticStruct.java
3. Check or run DefaultFunctionEncoderTest.testArrayInStruct()

Why is it needed?

Oct 2021 (https://github.com/web3j/web3j/issues/1526) Dec 2021 (https://github.com/web3j/web3j/issues/1588), there was various reports but not fixed yet. I also faced same issue and found how to fix.

Please kindly consider and review. Hopefully merge into next release.

~~checking build status~~ ✅ Done.

Both StaticArray and DynamicArray have the same problem, there should be the same solution to it.

expect uint256[2][] but got staticarray2[]

When it comes to StaticArray0 or DynamicArray contains nothing, just check the size of values in advance to see if should use getTypeAsString or not.

Due to #1738 merging, My PR is unnecessary anymore. So I closed it.
