feat: add ArrayData::new_default and change ArrayData::new_null for Struct and FixedSizeList to not have nulls in the children

[rluvaton]

Which issue does this PR close?

Relates to:

• StructArray allow to build with child that have nulls but for non nullable field #9302
• https://lists.apache.org/thread/7gbqjwykh1ob3xbvwph3ljsdl5c7kxpd

Rationale for this change

ArrayData::new_null when called for Struct or FixedSizeList data type will create nulls for the children as well
even when the children are marked as non nullable.

while nothing in the spec forbid it, it is allowed but not very ideal, so trying to reduce the chances that this is happening.

What changes are included in this PR?

Created new ArrayData::new_default function that create array data with specific length with default values, and updated Struct data type and FixedSizeList in ArrayData::new_null to call it for its fields so we wont create StructArray and FixedSizeListArray with null children for non nullable fields

Are these changes tested?

Yes

Are there any user-facing changes?

new function and maybe change of behavior for new_null if it was dependent upon
