Phobos has recently gotten a primitive way to run betterC tests

Now, it would be really cool if we can annotate existing tests with e.g.
`@betterCTest` and thus ensure that those tests work with -betterC (i.e.
extract them and run them with a minimal test runner.
a) @betterC
Probably too popular and would lead to too many conflicts.
Shouldn't be any conflict because the "betterC" symbol would be in a
different module.
b) @TestBetterC
c) @betterCTest || @bettercTest
Would probably be defined a enum somewhere in `std.internal`
d) @("betterC")
A bit ugly and harder to work with. If we ever want to name the
unittests in Phobos, this will make it harder.
I really hate that this is possible to do with UDAs. We should avoid
this as much as possible.
At some point we might also want to test whether something runs even
without any runtime (https://github.com/dlang/phobos/pull/6641), so e.g.
`@baremetalTest` might be defined too.
My favorite is (c) - any objections?
See also: https://github.com/dlang/tools/pull/357 (implementation of the
test extraction filter for UDAs)
I would say, if it's only for internal use then it can be placed in
`std.internal` with the `package` protection. If you want this to be
used outside of Phobos then I recommend putting it in `core.attribute`
in druntime, since that already exists.
