Support semantic logging

[mregen]

• For EventSource and legacy logger refactor logging to support the built in LogValueFormatter, which provides the format strings suitable for string.Format.
• Breaking change: For TraceEvent this is a breaking change, because there is no implementation yet to support to provide the reformatted format string. With this implementation if a logging framework is used which supports the semantic logging, there is no issue. With frameworks which do not understand semantic logging strings(e.g. log4net) it is a breaking change, string.format will throw exceptions --> move to ILogger hook using SetLogger.
• Warning: When Microsoft.Extensions.Logger based loggers are used, format strings must follow this convention:
  i) All variable entries must follow order and count up, e.g. "{0} -- {1}" etc., no mix of "{2}--{0}"
  ii) in the same way the args must follow this strict ordering.
• Format strings will be changed by future PR to include the semantic values.
