Adds a mechanism for generating test2json test artifacts from and validating them against a real test. If a .test file has a corresponding .src file, TestGolden will now treat the .src file as a script test, executing it and verifying that the output matches the contents of the .test file. Running TestGolden with the -update flag will also regenerate .test files if they have a corresponding .src file.
Capturing the output of the script test in this way required making minor changes to cmd/internal/script/scripttest.
This was motivated by CL 601535 (golang/go#62728). Specifically, testing that CL required adding src/cmd/internal/test2json/testdata/frameescape.test which has a multitude of non-printing characters and thus must be generated by executing `go test`. Using a script test to generate the test file is more reliable than doing it by hand.

They are very slow: taking them out of the cmd/go test suite makes the
go command tests go from about 80 seconds to run on my system, to about
50 seconds to run.

Add in automatic README generation and README consistency checking for
the cmd/compile and cmd/link script tests. This code is adapted from
the similar facility in cmd/go (e.g. scriptreadme_test.go); the README
helps folks writing new tests understand the mechanics.
Updates #68606.

Introduce a new function AddToolChainScriptConditions that augments a
default "script.Cond" set with a collection of useful conditions,
including godebug/goexperiment, cgo, race support, buildmode, asan,
msan, and so on. Having these conditions available makes it easier to
write script tests that deal with specific build-flavor corner cases.
The functions backing the new conditions are helper functions migrated
over from the Go command's script test setup.
Updates #68606.

Add top level apis to provide a general-purpose "script test" runner
for clients within cmd, e.g. tools such as compile, link, nm, and so
on. This patch doesn't add any uses of the new apis, this will
happen in follow-on CLs.
