JACOBIN-645 throw.go, frames.go, interpreter.go

[texadactyl]

frames.FormatFQN:

// From the given frame, return the FQN as a formatted string.
func FormatFQN(fr *Frame) string {
	return fmt.Sprintf("%s.%s%s", util.ConvertInternalClassNameToUserFormat(fr.ClName), fr.MethName, fr.MethType)
}

throw.go: amended to use FormatFQN consistently.

interpreter.go: amended to rely on ThrowEx to supply FQN information.

Also, remove redundant FQN announcement in:

• gfunction/gfunctionExec.go
• native/nativeFuncExec.go

NOTE: run.go runThread untrapped panic handling has not yet been addressed.
