0023384: Translate sub-shape names between XDE document and STEP

Browse Source 
Sub-shapes naming translation between XDE and STEP implemented as an optional mode of Reader/Writer.
New static variables are now available: write.stepcaf.subshapes.name for Writer and read.stepcaf.subshapes.name for Reader (both have 0 values by default).
XOpen command implemented in scope of XDEDRAW asset.

Added test case bugs xde CR23384
