Code Quality: `FileLogger` should send logs to a `BackgroundService`

[gumbarros]

Description

FileLogger should send logs to a BackgroundService because ILogger is not meant to do IO operations.

Concerned code

https://github.com/files-community/Files/blob/39c2f9cb4ebf16c6ad21f1737672b4fac829eae4/src/Files.Shared/Utils/Logger/FileLogger.cs

Gains

• Better performance, logging would not block the app thread writing to the file
• Separations of concerns, ILogger is meant just to log the information, another class needs to do the heavy job

Requirements

• Removing the IO operations from ILogger
• Create a BackgroundService to run the IO operations requested by a buffer
