Fixes#8763: render bug: pure enums not handled correctly
Fixes#8762: render bug: binary operators called with quotes rendered incorrectly
FIxes#8761: render bug: inversion of operator priorities
When an empty nkArgList `varargs[untyped]` is passed around it is now
reused for efficiency sake and to prevent the introduction of a spurious
element: before this commit we'd pass the caller a
nkArgList[nkHiddenStdConv[nkBracket]] node instead of just an empty
nkArgList.

* add experimental: dynamicBindSym
The example is a proof-of-concept logging library, allowing you to define
lexically-scoped environments where certain logging attributes are applied
automatically to all logging statements.
fixes tmacro1 (use of `bindSym` inside static blocks)
This allows you to pass a template or a macro to another macro
which can then inspect the implementation of the former template/macro
using `getImpl`.
Since templates can be freely redefined, this allows you to treat
their symbols as compile-time variables that have lexical scope.
A motivating PoC example for a logging library taking advantage of
this will be provided in the next commit.
Implementation details:
* The name of a template or a macro will be consider a symbol if
the template/macro requires parameters
* For parameterless templates/macros, you can use `bindSym`, which
was extended to also work outside of compile-time procs.
* Added codeRepr and dumpCode to the macros module.
This allows those writing macros to write examples, get the code to generate the AST for that example, and then modify that code to be dynamic with the macro function.
This commit returns to a bit less strict checking of the number
of macro arguments, because some old immediate macros rely on a
behavior where even the arity of the macro is not being checked.
It may be better if such macros are just declared to use varargs[expr],
but this remains for another day.
