Add Visual Studio Code keymap

[king-407]

Closes #6458.

Adds a Visual Studio Code keymap profile for NetBeans.

This change registers a new Visual Studio Code keymap using the existing NetBeans keymap infrastructure. The profile adds common VS Code-style shortcuts for editor actions, navigation, search, project actions, terminal access, and debugging.

It also adds a macOS-specific keybinding file so shortcuts follow Mac platform conventions where needed.

The shortcuts are mapped to existing NetBeans actions rather than introducing new action implementations.

Local verification:

Comparing this against what I had in #9672, here's what might be worth pulling in (and a couple of things worth double checking):

Shortcuts from the official VS Code reference that aren't mapped yet:

• Code folding entirely: collapse-fold (Ctrl+Shift+[), expand-fold (Ctrl+Shift+]), collapse-all-folds (Ctrl+K Ctrl+[), expand-all-folds (Ctrl+K Ctrl+])
• Indent/outdent line: shift-line-right (Ctrl+]), shift-line-left (Ctrl+[)
• Scroll line up/down: scroll-up (Ctrl+Up), scroll-down (Ctrl+Down)
• Add/remove line comment as distinct from toggle: comment (Ctrl+K Ctrl+C), uncomment (Ctrl+K Ctrl+U)
• Peek Definition: goto-source (Alt+F12)
• Format selection: format bound again to (Ctrl+K Ctrl+F), alongside Shift+Alt+F for the whole document
• Trim trailing whitespace: remove-trailing-spaces (Ctrl+K Ctrl+X)
• Expand/shrink selection: select-element-next (Shift+Alt+Right), select-element-previous (Shift+Alt+Left)
• Close editor (Ctrl+F4) and split editor (Ctrl+) don't seem to be mapped at all yet
• Quick Fix (Ctrl+.): worth adding as a global shadow pointing at Actions/Source/org-netbeans-modules-editor-hints-FixAction.instance, using D-PERIOD so it resolves to Cmd+. on Mac too (the DTD parses . as VK_PERIOD, C-DOT/VK_DOT isn't a real key, that's actually what tripped up the earlier PR)

Things your PR already has that I'd missed: redo, zoom-text-in/zoom-text-out, clipboard-history, the editor-level in-place-refactoring binding on F2 (I only had the global rename shadow, so in my version F2 wouldn't do in-place symbol rename inside the editor), and complete-line on Ctrl+Shift+Enter. Worth keeping those.

One thing worth double-checking while you're in there: DS-O is currently mapped to Open Project, but the official shortcut sheet has Ctrl+Shift+O as "Go to Symbol" (Actions/Edit/org-netbeans-modules-jumpto-symbol-GoToSymbol.instance), so that one might be worth remapping.

Happy to answer questions on any of this, I went through the official VS Code Windows/Mac shortcut references and cross-checked action names against BaseKit/EditorActionNames and the existing Idea/Eclipse profiles while working on #9672.

Thanks for the detailed comparison.

I have incorporated the verified mappings from your suggestions, including folding, indent/outdent, scroll up/down, comment/uncomment, format selection, trim trailing whitespace, peek source, Quick Fix, Go to Symbol, and Find Usages.

I also kept the mappings that were already present in this PR, such as redo, zoom, clipboard history, in-place rename, and complete-line.

I skipped the editor split binding for now because I could not verify the exact NetBeans editor action name safely from the existing keymap/action registrations.
