Add check for explicit lifetime when initialising static variables.
...
If a static variable declared in a task, function, or block has an
initialisation expression, SystemVerilog requires the declaration to
have an explicit static lifetime. This is supposed to be a compile
error, but for now just output a warning.
Implementing this required adding support in the parser for explicit
lifetimes in variable declarations. For now, just output an error if
the user asks for a lifetime that isn't the default for that scope.
