fix: Allow double and float types to be rollupable (#2311)

[mofojed]

• Cherry-pick of Web UI should allow using doubles as rollup key columns #2295 to v0.85
• We had this restriction in the UI, but the engine can actually handle it
• Tested with doubles, floats
• Tested with the following tables:

from deephaven import empty_table

doubles = empty_table(1_000_000).update_view(["Group = i*10.4", "N = (i % 347)*0.1", "M = (i % 29)*10.2", "Value=i*2.4", "Weight=i*4.2"])
floats = empty_table(1_000_000).update_view(["Group = i*10.4", "N = (float)(i % 347)*0.1", "M = (float)(i % 29)*10.2"
, "Value=(float)i*2.4", "Weight=(float)i*4.2"])

• Updated e2e tests and unit tests
