Update for proposed DynamicPPL 0.32

[penelopeysm]

DPPL 0.32: TuringLang/DynamicPPL.jl#733

This PR:

• Re-adds the tests that were straight up removed from the DPPL/Turing integration tests. Note, this basically just means that I copied test/turing/compiler.jl in DPPL to test/dynamicppl/compiler.jl here because the remaining integration tests were successfully moved to DPPL's own test suite.
• Updates the names of DynamicPPL demo model (see link above)
• Updates compat entries and version number

@yebai If you could take a look at this, once we get this merged it will clear the way for CI to run properly on the Gibbs PR :)

Right now it's timing out because of the submodel issue on DPPL (TuringLang/DynamicPPL.jl#750)

Thanks @penelopeysm -- I left a few minor suggestions above.
