all: wire up swisstable maps

Browse source 
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.
