Title: [Extensions] Add command line switch xwalk-extension-cmd-prefix

This will prepend the contents of this flag to the command line
when starting extension process, it works as same as the switch
"--renderer-cmd-prefix", could be useful if we need to debug
the extension process at its very beginning.
Useful values might be "valgrind" or "xterm -e gdb --args".
