* Logging: Refactor log targets into Ryujinx.Common * Logger: Implement JSON Log Target * Logger: Optimize Console/File logging targets Implement a simple ObjectPool to pool up StringBuilders to avoid causing excessive GCing of gen1/2 items when large amounts of log entries are being generated. We can also pre-determine the async overflow action at initialization time, allowing for an easy optimization in the message enqueue function, avoiding a number of comparisons. * Logger: Implement LogFormatters * Config: Refactor configuration file and loading * Config: Rename to .jsonc to avoid highlighting issues in VSC and GitHub * Resolve style nits * Config: Resolve incorrect default key binding * Config: Also update key binding default in schema * Tidy up namespace imports * Config: Update CONFIG.md to reflect new Config file
