Austin Clements b079640404 misc/cgo/test: simplify for module mode
When we were first introducing module mode, CL 163418 moved many of
the tests in misc/cgo/test into their own test binary under testdata
so misc/cgo/test continued to work in both GOPATH mode and module
mode. This introduce a somewhat complicated test driver into
misc/cgo/test. Since the misc/cgo/test test had to invoke "go test" as
a subprocess, this required care to thread any build flags down into
the subprocess. The output from any failures of the sub-process was
also less than ideal.

Now that we don't have to worry about running these in GOPATH mode any
more, this CL moves all of the tests back into misc/cgo/test and drops
the test driver.

There are two slight complications:

- Test41761 was added after this split and has a C type "S" that's
  also present in misc/cgo/test itself. We rename that to keep that
  test working.

- TestCgo in go/internal/srcimporter now fails to import misc/cgo/test
  because misc/cgo/test now contains imports of other "misc" module
  packages and the importer it sets up isn't configured to allow that.
  We fix this by setting up a build context that's configured for
  this.

Preparation for #37486.
