[ARMeilleure] Address dotnet-format issues (#5357)

* 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

* Silence dotnet format IDE0052 warnings

* Address or silence dotnet format IDE1006 warnings

* Address or silence dotnet format CA2208 warnings

* Address dotnet format CA1822 warnings

* Address or silence dotnet format CA1069 warnings

* Silence CA1806 and CA1834 issues

* Address dotnet format CA1401 warnings

* Fix new dotnet-format issues after rebase

* Address review comments

* Address dotnet format CA2208 warnings properly

* Fix formatting for switch expressions

* 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

* Revert formatting changes for OpCodeTable.cs

* Enable formatting for a few cases again

* Format if-blocks correctly

* Enable formatting for a few more cases again

* Fix inline comment alignment

* Run dotnet format after rebase and remove unused usings

- analyzers
- style
- whitespace

* Disable 'prefer switch expression' rule

* Add comments to disabled warnings

* Remove a few unused parameters

* Adjust namespaces

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

* Start working on disabled warnings

* Fix and silence a few dotnet-format warnings again

* Address IDE0251 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

* Remove unnecessary formatting exclusion

* Add unsafe dotnet format changes

* Change visibility of JitSupportDarwin to internal
