templatespec: create a factory function for each type there is

Most of the arguments to the `templatespec` constructor are mutually
exclusive, so each combination creates a different type of
templatespec. Let's clarify that by creating factory functions.

I've left the callers in `logcmdutil` unchanged for now because they
are more complex and `logcmdutil.templatespec()` is slightly higher
level in that it is specific to changesets.

My larger goal is to add support frozen binaries (specifically
PyOxidizer) by adding a specific type of `templatespec` for built-in
templates. That will get its own factory function.

== New Features ==

 * The amend extension supports the `--currentuser` argument.

 * The amend extension supports the `--close-branch` argument.

 * The amend extension supports the `--secret` argument.

 * The uncommit extension supports the `rewrite.update-timestamp` config option.

== New Experimental Features ==


== Bug Fixes  ==


== Backwards Compatibility Changes ==

 * A shell that supports `$(command)`` syntax for command substitution is now
   required for running the test suite. The test runner normally uses
   `sh`, so if that is a shell that doesn't support `$(command)` syntax,
   you can override it by setting `$HGTEST_SHELL` or by passing it to
   `run-tests.py --shell <shell>`.

 * The (experimental) narrow extension's wire protocol changed. If
   you're using it, you'll need to make sure to upgrade server and
   client at the same time.

== Internal API Changes ==
