Use the new SwissTable-based map in internal/runtime/maps as the basis for the runtime map when GOEXPERIMENT=swissmap. Integration is complete enough to pass all.bash. Notable missing features: * Race integration / concurrent write detection * Stack-allocated maps * Specialized "fast" map variants * Indirect key / elem For #54766.
