Support logpoint with the debug protocol changes #272

https://code.visualstudio.com/updates/v1_22#_debug-adapter-protocol

VSCode java debug protocol has the logPoint support and some other changes:
Logpoint support

The newly introduced Logpoints are surfaced in the Debug Adapter Protocol as a new attribute logMessage on the SourceBreakpoint and as a new capability supportsLogPoints. A debug adapter that supports Logpoints returns true for the supportsLogPoints capability and does not 'break' (stop) for a non-empty logMessage attribute but logs the message instead. Expressions within curly braces ('{...}') are evaluated and the result replaces the '{...}' in the log message.

New clientName attribute for initialize request

The frontend can use a new optional attribute clientName on the initialize request to pass the human readable name of the frontend to the debug adapter.

New terminateThreads request

A new terminateThreads request can be used by front ends to terminate one or more threads. A corresponding supportsTerminateThreadsRequest capability signifies that the debug adapter supports the request.

New setExpressionrequest

The new setExpression request can be used to assign a value to an assignable expression (aka "l-value"). A corresponding supportsSetExpression capability signifies that the debug adapter supports the request.

New preserveFocusHinton stopped event

A true-ish preserveFocusHint on the stopped event suggests to the front end that the stopped event should not change the focus.
