Bugfix/LS24004086/MOVEA from Array field to Standalone

[davidepalladino-apuliasoft]

Description

This work adds the capability to use MOVEA from an array declared as DS' field to a Standalone definition. For example:

     D AUTOAP        E DS                  EXTNAME(AUTOAP0F)
     D  AU1                   61     80         DIM(10)
     D £AUATI          S             20

     ...

     C                   MOVEA     AU1           £AUATI

Also, provides to fix the "overlay" of a DS field, imported by using EXTNAME, and another declared with offset. Under the hood, by considering previous example, we have a DS built with fields provided from AUTOAP0F and a new field (AU1) declared with offset. This offset corresponds with some field provided from AUTOAP0F. So, the value for AU1 might be the value for another field.

Technical notes

For the first cause, related to MOVEA, I fixed the problem by adding to ProjectedArrayValue class the implementation for elementSize, takeAll, takeFirst, takeLast.

For the second cause, "overlay" of two field by using EXTNAME:

1. I improved the construction of knowDataDefinitions from files by ignoring data definitions declared without EXTNAME;
2. I provided to RpgParser.Parm_fixedContext.toFieldInfo the fields declared in a file imported with EXTNAME.
