Add new launch configuration to allow the debugger to connect to debuggable apps and Java processes running on the device.

The default configuration uses a processId value of "${command:PickAndroidProcess}" to automicatically invoke a new extension command to list debuggable processes running on the connected device.

The attach launch config requires the appSrcRoot in order to identify breakpoint locations.
To ensure all breakpoints are loaded after attaching, a list of all currently loaded classes is now retrieved upon connection.
VSCode quick-pick lists are used to select which device (if there's more than one) and which process should be attached to.
The adb jdwp command never terminates - we use a timeout value to limit how long we search for debuggable processes.
Retrieving the package names of the PIDs uses a shell for loop which requires multiple socket reads to obtain all of the output. A new untilclosed flag has been added to the socket functions to allow this, which keeps reading from the socket until the other side closes it.
