Sampling issues due to Aeppl logp assertions

[ricardoV94]

As discussed in aesara-devs/aeppl#84, Aeppl introduced explicit Aesara asserts in the logp graphs of several distributions. Until a rewrite is implemented there or here, we can expect to see some AssertionErrors crashing pm.sampling.

For instance, one of the test regression documented in #5088 was precisely because of this.

Also a good opportunity to turn the model.check_bounds flag into a compile-time optional rewrite.
