Add workflow to automatically check code style issues for PRs (#4670)

* Add workflow to perform automated checks for PRs

* Downgrade Microsoft.CodeAnalysis to 4.4.0

This is a workaround to fix issues with dotnet-format.
See:
- https://github.com/dotnet/format/issues/1805
- https://github.com/dotnet/format/issues/1800

* Adjust editorconfig to be more compatible with Ryujinx code-style

* Adjust .editorconfig line endings to match .gitattributes

* Disable 'prefer switch expression' rule

* Remove naming styles

These are the default rules, so we don't need to override them.

* Silence IDE0060 in .editorconfig

* Slightly adjust .editorconfig

* Add lost workflow changes

* Move .editorconfig comment to the top

* .editorconfig: private static readonly fields should be _lowerCamelCase

* .editorconfig: Remove alignment for declarations as well

* editorconfig: Add rule for local constants

* Disable CA1822 for HLE services

* Disable CA1822 for ViewModels

Bindings won't work with static members, but this issue is silently ignored.

* Run dotnet format for the whole solution

* Check result code of SDL_GetDisplayBounds

* Fix dotnet format style issues

* Add missing trailing commas

* Update Microsoft.CodeAnalysis.CSharp to 4.6.0

Skipping 4.5.0 since it breaks dotnet format

* Restore old default naming rules for dotnet format

* Add naming rule exception for CPU tests

* checks: Include all files before excluding paths

* Fix dotnet format issues

* Check dotnet format version

* checks: Run dotnet format with severity info again

* checks: Disable naming style rules until they won't crash the process anymore

* Remove unread private member

* checks: Attempt to run analyzers 3 times before giving up

* checks: Enable naming style rules again with the new retry logic
