runtime/pprof: map allocation runtime frames no longer hidden in 1.24

[prattmic]

runtime/pprof hides "runtime" frames in heap profiles, so allocations in maps appear at the map assignment location in the calling code, but not in runtime.mapassign itself.

As you can see, runtime/pprof is defining "runtime frames" as symbols starting with runtime., but much of the new map implementation is in internal/runtime/maps., so frames inside the map implementation are still appearing.
