  [CostModel] Add -cost-kind=all costmodel output (#130490)

In order to make the different cost model kinds easier to test, and to
manage the complexity of all the different variants, this patch
introduces a -cost-kind=all option that will print the output of all
cost model kinds. It feel especially helpful for tests that already have
multiple run lines (with / without +fullfp16 for example).

It currently produces the output:
```
Cost Model: Found costs of RThru:1 CodeSize:1 Lat:3 SizeLat:1 for: %F16 = fadd half undef, undef
```

The output is collapsed into a single value if all costs are the same.
Invalid costs print "Invalid" via the normal InstructionCost printing.

Two test files are updated to show some examples with
-intrinsic-cost-strategy=type-based-intrinsic-cost and Invalid costs.
Once we have something we are happy with I will try to use this to
update more tests, as in b021bdbb3997ef6dd13980dc44f24754f15f3652 but
for more variants.
