[Ryujinx.Graphics.Nvdec] Address dotnet-format issues (#5369)

* dotnet format style --severity info

Some changes were manually reverted.

* Restore a few unused methods and variables

* Address most dotnet format whitespace warnings

* Apply dotnet format whitespace formatting

A few of them have been manually reverted and the corresponding warning was silenced

* Add previously silenced warnings back

I have no clue how these disappeared

* Add comments to disabled warnings

* Simplify properties and array initialization, Use const when possible, Remove trailing commas

* Address IDE0251 warnings

* Revert "Simplify properties and array initialization, Use const when possible, Remove trailing commas"

This reverts commit 9462e4136c0a2100dc28b20cf9542e06790aa67e.

* dotnet format whitespace after rebase

* First dotnet format pass
