RFR: 8343224: print/Dialog/PaperSizeError.java fails with MediaSizeName is not A4: A4 [v2]

[GennadiyKrivoshein]

> Fix for https://bugs.openjdk.org/browse/JDK-8343224, print/Dialog/PaperSizeError.java fails with MediaSizeName is not A4: A4.
> 
> **Reason of the bug:**
> The reason for the regression bug is a missed check for the standard media existence during CustomMediaSizeName creation.
> After the JDK-7001133 new MediaSize is created, regardless of whether a standard media size exists. 
> 
> For example, if a printer's PPD has two media with the same size, close to "iso_A4," with a small difference.
>          *PaperDimension A4/A4:             "595 842"
>          *PaperDimension BrA4_B/A4 (Borderless):  "595 842"
> After processing the first line, the MediaSize will contain the new size "A4" because of the missed check, and CustomMediaSize will match the "iso_a4" standard media size.
> After processing the second line, the MediaSize will contain the new size "BrA4_B", and CustomMediaSize will match not the "iso_a4" but the previously added "A4", because it was added by mistake and its size is exactly the same as "BrA4_B".
> 
> **Fix description:**
> Create new MediaSize if there is no any other MediaSize with the same size.
> 
> **Tests:**
> OS: MacOS 12, Linux Ubuntu 22, Windows 11. 
> open/test/jdk/java/awt/print/Dialog/PaperSizeError.java
