Add EditableResources (editable Resources) implementation and unit tests

[shai-almog]

Motivation

• Provide an editable variant of Resources usable in environments that lack the JavaSE designer classes.
• Enable programmatic creation, modification and saving of resource files while intentionally excluding complex resource types.

Description

• Add EditableResources implementing an editable Resources with open(InputStream), save(OutputStream), setImage, setData, setL10N, getData, isModified, and clear behavior.
• Override startingEntry and createImage to reject unsupported types and to handle encoded image subtypes and multi-image entries.
• Implement image writing (writeImage) and localization serialization (saveL10N), and raise UnsupportedOperationException for GUI builder, timeline, SVG, and indexed-image resources.
• Add EditableResourcesTest unit tests exercising setter rejection paths, open rejection of unsupported entries and image subtypes, and a save/read round-trip for supported IMAGE/DATA/L10N types.

Testing

• Added maven/core-unittests/src/test/java/com/codename1/ui/util/EditableResourcesTest.java which contains tests for unsupported setters, open rejections, image-subtype rejection, and save round-trip with Resources.
• Ran the module unit tests (the EditableResourcesTest suite) and they completed successfully.
