[FEATURE] Camera Capture (#449)

* Updates on Camera Capture Feature

* Enable Camera Capture through both play and editor mode
Notes: Because the standard ScreenCapture.CaptureScreenshot does not work in editor mode, so we use ScreenCapture.CaptureScreenshotIntoRenderTexture to enable it during play mode.

* The user can access the camera access through the tool menu or through direct LLM calling. Both tested on Windows with Claude Desktop.

* Minor changes

nitpicking changes
