>> 
>> **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
>> test/jdk/javax/print/CustomMediaSizeNameOOMETest.java
>> All tests from the test/jdk/javax/print/
