Previously, if an example test invoked runtime.Goexit, it would
pass yet hang until a timeout, while regular tests that invoke
runtime.Goexit do fail. This change removes that inconsistent
behavior and makes such example tests fail, and panic with an
indication of having invoked runtime.Goexit.

os.Pipe is not implemented on wasm/js so for that purpose use
a temporary file for js/wasm. This change creates two versions
of runExample:
* runExample verbatim that still uses os.Pipe for non js/wasm
* runExample that uses a temporary file
Also added a TODO to re-unify these function versions back into
example.go wasm/js gets an os.Pipe implementation.

I grepped for "bytes.Buffer" and "buf.String" and mostly ignored test
files. I skipped a few on purpose and probably missed a few others,
but otherwise I think this should be most of them.

For example, testing the current directory:
$ go test -run XXX
testing: warning: no tests to run
PASS
ok testing 0.013s
$
And in a summary:
$ go test -run XXX testing
ok testing 0.013s [no tests to run]
$
These make it easy to spot when the -run regexp hasn't matched anything
or there are no tests. Previously the message was printed in the "current directory"
case when there were no tests at all, but not for no matches, and either way
was not surfaced in the directory list summary form.
Fixes#15211.

Adds a type of output to Examples that allows tests to have unordered
output. This is intended to help clarify when the output of a command
will produce a fixed return, but that return might not be in an constant
order.
Examples where this is useful would be documenting the rand.Perm()
call, or perhaps the (os.File).Readdir(), both of which can not guarantee
order, but can guarantee the elements of the output.

Delete the colon from RUN: for examples, since it's not there for tests.
Add spaces to line up RUN and PASS: lines.
Before:
=== RUN TestCount
--- PASS: TestCount (0.00s)
=== RUN: ExampleFields
--- PASS: ExampleFields (0.00s)
After:
=== RUN TestCount
--- PASS: TestCount (0.00s)
=== RUN ExampleFields

This was brought to my attention because a user thought that because
the file was named "example.go" it served as an example of good coding
practice. It's not an example, of course, but may as well use a more
idiomatic style anyhow.
