docs: drop custom envvar directive

The custom envvar directive is strange. It overloads the global
namespace, where there's already a well-known envvar directive, but the
envvar role won't resolve to envvars defined using the custom directive.

It's not really critical to declare the type and default value here, and
many descriptions already include this. Let's just use the plain one,
and let the description take care of the details where needed.

If set, this variable will cause the :ref:`trace` output to be written to the
specified file. Paths may be relative or absolute; relative paths are relative
to the working directory. For example, setting it to "trace.xml" will cause
the trace to be written to a file of the same name in the working directory.

If enabled while :ref:`trace` is active, this variable specifies that the threaded context
