add support for Go 1.25 and drop support for 1.24
While strictly speaking it would be okay to leave Go 1.24 support
in place for the time being, we are behind on a few tasks at the moment
so it's best to keep the setup at master simpler for the next release.
Go 1.25 already came out two weeks ago, and it seems to have been
a fairly smooth release, so I don't suspect any end users will have
trouble upgrading to it.
Note that two changes were necessary for garble to work on Go 1.25.0.
First, we stop deduplicating runtimeAndLinknamed with runtimeAndDeps.
Otherwise, for GOOS=windows, internal/runtime/cgroup would be missing
as it is a //go:linkname target from runtime on all platforms,
but it is not transitively imported from runtime on GOOS=windows.
Second, the testing/synctest package is now part of std,
and it is a //go:linkname target from the testing package
but not a transitive import from it. Teach appendListedPackages that,
when loading all packages for a `go test` run, it should load
the new testing/synctest package too.
Fixes #968.

redesign benchmark to be more useful and realistic
First, join the two benchmarks into one.
The previous "cached" benchmark was borderline pointless,
as it built the same package with the existing output binary,
so it would quickly realise it had nothing to do and take ~100ms.
The previous "noncached" benchmark input had no dependencies,
so it was only really benchmarking the non-obfuscation of the runtime.
All in all, neither benchmark measured obfuscating multiple packages.
The new benchmark reuses the "cached" input, but with GOCACHE="*",
meaning that we now obfuscate dozens of standard library packages.
Each iteration first does a built from scratch, the worst case scenario,
and then does an incremental rebuild of just the main package,
which is the closest to a best case scenario without being a no-op.
Since each iteration now performs both kinds of builds,
we include a new "cached-time" metric to report what portion of the
"time" metric corresponds to the incremental build.
Thus, we can see a clean build takes ~11s, and a cached takes ~0.3s:
name time/op
Build-16 11.6s ± 1%
name bin-B
Build-16 5.34M ± 0%
name cached-time/op
Build-16 326ms ± 5%
name sys-time/op
Build-16 184ms ±13%
name user-time/op
Build-16 611ms ± 5%
The benchmark is also no logner parallel; see the docs.
Note that the old benchmark also reported bin-B incorrectly,
as it looked at the binary size of garble itself, not the input program.
