compiler: support Go 1.27 generic methods via x/tools upgrade

Browse Source 
Go 1.27 adds generic methods (golang/go#77273). golang.org/x/tools
go/ssa v0.42.0 does not instantiate them: objectMethod only applies
receiverTypeArgs and ignores method-level type parameters, so a call
such as (*math/rand/v2.Rand).N resolves to the abstract generic method
and its body reaches createConst with a type-parameter-typed zero
constant, triggering "panic: expected nil interface constant".

Upgrade golang.org/x/tools to v0.47.0, whose go/ssa returns nil from
MethodValue for generic methods and instantiates method-level type
parameters. No compiler changes are required.

Since x/tools v0.47.0 requires Go 1.25, raise the minimum supported Go
version from 1.24 to 1.25.
