[ETW] Add table name mapping for Logs other than the default Log table

[ThomsonTan]

Fixes #2680, this is the option 1 in the proposal with minor extension on defining a mapping for the table names. This makes it more flexible for the SDK users for configure the table name in the ETW exporter, without changing the API call in the instrumented libraries.
