This increases consistency and saves a bit of code, but more
importantly, it makes it much easier to switch between these APIs
while refactoring tests.

This reverts part of commit d4c681a937
(#20764).
The ternary conditions are necessary because __Rewire__ can be (and in
fact is) used to patch non-exported variables.

I also remove a conditional here that's not necessary. For
anything that's obviously a template in static/templates,
we now create a stub implementation that behaves according
to whether we're stubbed or being included as a partial.
We now only expose mock_template as a helper in run_test.
This has the following advantages:
* less boilerplate at the top of the file
* more surgical control with setting exercise_templates
* no more "f" hack (or render_foo consts)
* we force devs to explicitly mock the template
See frontend_tests/zjsunit for the substantive changes.
All the changes to the tests are very mechanical in nature.
There is still no need for mock_template to reach into the internals
of mock_cjs. Make it a normal caller of mock_cjs.
This is basically the same as 60f5a00c09
(#18804), because the same abstraction violation was since
reintroduced in the same way.

If you call mock_template(fn, true), we will
call the actual template code and pass it to your
stub for verification.
We make this opt-in to prevent false positives
on template line coverage.
We special-case our handling of static/js/templates.js,
since it's important that all of our tests have
the Zulip-specific handlers for Handlebars pre-registered.
This runs in roughly the same amount of time as the
previous commit.
This is necessary for the new `mock_template` helper added in
97ad6b6b62 to work correctly without
leaks, since it uses `mock_cjs` under the hood.
This logic was added in 216493aae8.

This is prep toward allowing individual tests
to fail while continuing to run the test suite.
Most of the steps in namespace.finish() could
be put in a `finally` block, but once a test
fails, there's no reason to complain about
unused mocks, since there are bigger things
to address.
Factor out mock_cjs from mock_esm because adding __esModule prevents
mocks for CJS modules from being imported correctly.

Use fully resolvable request paths because we need to be able to refer
to third party modules, and to increase uniformity and explicitness.

I now let folks override the same target multiple
times inside of `with_overrides` (and then indirectly
inside of `run_test`.)
I may re-impose this restriction in the future, since
most violations are due to code smells, but there are
a few legitimate use cases for this, and the code
can handle it, plus I want to remove some other
ugliness first.
We now just use a module._load hook to inject
stubs into our code.
For conversion purposes I temporarily maintain
the API of rewiremock, apart from the enable/disable
pieces, but I will make a better wrapper in an
upcoming commit.
We can detect when rewiremock is called after
zrequire now, and I fix all the violations in
this commit, mostly by using override.
We can also detect when a mock is needlessly
created, and I fix all the violations in this
commit.
The one minor nuisance that this commit introduces
is that you can only stub out modules in the Zulip
source tree, which is now static/js. This should
not really be a problem--there are usually better
techniques to deal with third party depenencies.
In the prior commit I show a typical workaround,
which is to create a one-line wrapper in your
test code. It's often the case that you can simply
use override(), as well.
In passing I kill off `reset_modules`, and I
eliminated the second argument to zrequire,
which dates back to pre-es6 days.
