[Ryujinx.Graphics.OpenGL] Address dotnet-format issues (#5372)

* dotnet format style --severity info

Some changes were manually reverted.

* dotnet format analyzers --serverity info

Some changes have been minimally adapted.

* Restore a few unused methods and variables

* Silence dotnet format IDE0060 warnings

* Address or silence dotnet format IDE1006 warnings

* Fix IDE0090 after rebase

* 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

* Format if-blocks correctly

* Another rebase, another dotnet format run

* Run dotnet format after rebase and remove unused usings

- analyzers
- style
- whitespace

* Add comments to disabled warnings

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

* Start working on disabled warnings

* Address a few disabled IDE0060 warnings

* Silence IDE0060 in .editorconfig

* 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

* Address review feedback
