use tags instead of graph_rewrite_map in rangeify (#12110)

* use tags instead of graph_rewrite_map in rangeify

* new style, add realize

* metadata works

* simple failure

* fix

* loops

* stuff becomes a NOOP when you remove it

* stuff becomes a NOOP when you remove it

* tags on bufferize

* bmnist works

* locals don't work

* shippable

* fix some tests

* simpler map_realize

* remove const hack

* debuggable test

* broke

* assign test

* straight up bug

* wooo it passes

* sink shouldn't be there

* fix ops

* bmnist

* kv cache ish

* Set RANGEIFY context variable to 0

* should work normal

* better

* types

* hacks to fix test_symbolic

* pm_add_buffers

* tests should pass
