include/nuttx/macro.h: Let FOREACH_ARG() paste the argument index 
FOREACH_ARG() hands the position of each argument as the expression
"count - N", which can be used as a value but cannot be pasted into an
identifier, because "##" pastes a single token.  Hand it out as a
literal instead, so that an action macro can build a symbol name out of
it, which is what a subsystem needs when the link order of its objects
has to follow the declaration order.

The list is reversed through REVERSE_ARG() so that the position becomes
the level of the chain, and each step emits the recursion before its own
action so that the actions still come out in the order the arguments
were given.  This is how the same problem is solved upstream in Zephyr,
whose FOR_EACH_IDX() also reverses the list before walking a per arity
chain.

The index values are unchanged, so the arithmetic use keeps working:
NOTE_PRINTF_TYPES(), the only user in tree, produces the same tags for
every argument count.  It now supplies the leading zero itself, because
FOREACH_ARG() no longer expands to "0" when the list is empty.  An empty
list expanding to nothing is what lets an action expanding to
declarations be used at file scope.
