Software Components save removes packs/components from clayer files from other project contexts

[jthuangarm]

Current behavior, Steps to reproduce and Expected behavior

When editing the Software Components view for one project context and saving the changes, the extension removes all packs: and components: nodes from .clayer.yml files that belong to other project contexts.

Steps to reproduce

1. Use the example: https://github.com/Arm-Examples/Safety-Example-Infineon-T2G
2. Open Software Components for one cproject or one clayer, for example from Blinky.
3. Add an additional arbirtary pack, for example ARM::CMSIS-NN.
4. Save the Software Components view.
5. Check the .clayer.yml files used by the other "active" projects, for example Boot or TrafficLight.

The packs: and components: sections in unrelated .clayer.yml files are removed. This can later lead to errors such as:

board 'KIT_T2G-B-H_LITE:V1' was not found

because the board layer no longer references the Infineon BSP/DFP packs.

Expected behavior
Saving changes for one active context should only update the active project/context and its relevant layer files. It should not modify .clayer.yml files used only by other project contexts.
