Add default attribute to memory in cbuild-run.yml

[jthuangarm]

To address #2424

This pull request introduces support for marking memory regions as default in the project manager tool. In cbuild-run.yml default is located right before the from-pack: property under memory.

• Updated the JSON schema (common.schema.json) to define the new default property for memory objects.
• Modified ProjMgrRunDebug.cpp to read the default attribute when collecting settings and to write it when generating YAML output.

Pull request overview

This PR adds support for exposing the CMSIS-Pack default attribute on memory regions in generated .cbuild-run.yml output, enabling downstream tools (e.g., pyOCD RTT search) to identify “general-purpose” default memory.

Changes:

• Extend the projmgr common JSON schema to allow a new boolean default property on system-resources: memory entries.
• Collect the default attribute from pack memory definitions during run/debug settings collection.
• Emit default: true into generated .cbuild-run.yml reference outputs for default memory regions.
