Add option to enable HDR rendering in 2D

Browse Source 
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance

Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.

If [code]true[/code], enables debanding on the specified viewport. Equivalent to [member ProjectSettings.rendering/anti_aliasing/quality/use_debanding].

If [code]true[/code], 2D rendering will use a high dynamic range (HDR) format framebuffer matching the bit depth of the 3D framebuffer. When using the Forward+ renderer this will be a [code]RGBA16[/code] framebuffer, while when using the Mobile renderer it will be a [code]RGB10_A2[/code] framebuffer. Additionally, 2D rendering will take place in linear color space and will be converted to sRGB space immediately before blitting to the screen (if the Viewport is attached to the screen). Practically speaking, this means that the end result of the Viewport will not be clamped into the [code]0-1[/code] range and can be used in 3D rendering without color space adjustments. This allows 2D rendering to take advantage of effects requiring high dynamic range (e.g. 2D glow) as well as substantially improves the appearance of effects requiring highly detailed gradients. This setting has the same effect as [member Viewport.use_hdr_2d].
[b]Note:[/b] This setting will have no effect when using the GL Compatibility renderer as the GL Compatibility renderer always renders in low dynamic range for performance reasons.
