std.Target: Introduce Cpu convenience functions for feature tests.

Browse Source 
Before:

* std.Target.arm.featureSetHas(target.cpu.features, .has_v7)
* std.Target.x86.featureSetHasAny(target.cpu.features, .{ .sse, .avx, .cmov })
* std.Target.wasm.featureSetHasAll(target.cpu.features, .{ .atomics, .bulk_memory })

After:

* target.cpu.has(.arm, .has_v7)
* target.cpu.hasAny(.x86, &.{ .sse, .avx, .cmov })
* target.cpu.hasAll(.wasm, &.{ .atomics, .bulk_memory })
