[dev.typeparams] test: fix and update run.go's generics testing
In a late change to golang.org/cl/320609, while going back and forth
on the meaning of the boolean result value for "checkFlags", I got one
of the cases wrong. As a result, rather than testing both default
flags and -G=3, we were (redundanly) testing default flags and -G=0.
I ran into this because in my local dev tree, I'm using types2 even
for -G=0, and evidently one of the recent types2 CLs changed the error
message in fixedbugs/issue10975.go. Fortunately, there haven't been
any other regressions despite lacking test coverage.
So this CL cleans things up a bit:
1. Fixes that test to use -lang=go1.17, so types2 reports the old
error message again.
2. Renames "checkFlags" to "validForGLevel" so the boolean result is
harder to get wrong.
3. Removes the blanket deny list of all -m tests, and instead adds the
specific tests that are still failing. This effectively extends -G=3
coverage to another 27 tests that were using -m but already passing,
so we can make sure they don't regress again.
4. Adds a -f flag to force running tests even if they're in the deny
list, to make it easier to test whether they're still failing without
having to edit run.go.
