jduncanator d306115750 Logger and Configuration Refactoring (#573)
* 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
