fix: intermediate representation of array expression

[cieplypolar]

Before:

• Array expression was resolved immediately when the NODE.arrayExpr was encountered in the wgsl generator. Since the resulting snippet's value was a string, we couldn't really access array values.

Now:

• The NODE.arrayExpr returns an intermediate representation (ArrayExpression). Thereby, we delayed its resolution.

Additional changes:

• separated logic for calling struct and array schemas in NODE.call
• moved validation if elements of array are references to ArrayExpression
• aligned cloning logic for arrays in NODE.call
  -added/modified appropriate tests

Closes #2017.
