[ASTERIXDB-2615][*DB] Enable constant folding rule to determine when to fold

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

Currently, some functions are excluded from being evaluated at compile time in

constant folding rule. Those functions are maintained in a set. The reason for

excluding them is because they can produce records/lists in their "open" format

and constant folding them will make them "closed" which would lead to incorrect

results. Any time a new function is implemented, the developer would have to pay

attention and add their functions if they should be excluded, too.

The exclusion set should be removed. The constant folding rule should determine

from the output type of the function whether it can/should be folded or not.

- fixed an issue with StaticTypeCastUtil where it would not open up a field

when that field's value is a function call.

- modified casting items of lists to avoid casting open the item when it is

already in the opened up format.

- modified the type computer of object_remove_fields to handle constant

arguments (the 2nd argument which is the name of the fields) since the

argument can be constant folded now.

- modified field-access-by-index to handle evaluating it at compile time

(by constant folding rule) in the case where the object accessed is missing

(or non-object)

[NO ISSUE][FUN] Modify array functions to allow comparing complex

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

This change is to modify the array functions to compare complex

types like arrays and records. The change also includes a small

fix to IsomorphismVariableMappingVisitor where the

NestedTupleSourceOperator visit method would downcast the args

without checking first they are of the same operator types.

- changed test cases

- changed NullMissingTest to pass the args types for functions

that need them.

[FUN] fix array functions when args have ANY type

- user model changes: no

- storage format changes: no

- interface changes: no

details:

This is to fix the array functions that use type inferer

in order to infer the types of the arguments at compile time.

In some cases, the args could have ANY type at compile time

but they return the correct required type at runtime. This

patch handles such scenarios.
