feat(combobox): rewrite entire component & add virtual support

[H4ad]

Changes:

• Bunch of rewrite in the combobox simple component to simplify the code
• Add extensive testing
• Improved some default behavior (order of items, dividers being hidden when filter)
• Added support to virtualization
  • We have some cases on SigNoz that causes the component to behave poorly without virtualization.

@H4ad - just want to confirm if the below 2 cases are handled.

1. Clear selection (without opening the suggestions)
2. If a group doesn't have any items, is the group title shown or hidden ?

1. I didn't added support yet The support was added.
2. It will be hidden/filtered out
