BLD: conda-forge recipe

A conda-forge recipe would make it even easier to install dynamorio on many platforms

**Is your feature request related to a problem? Please describe.**
need: install a specific versions of dynamorio in a condaenv in a container

e.g. jupyter/docker-stacks docker-stacks-foundation installs mamba, which installs packages from conda-forge
https://github.com/jupyter/docker-stacks/blob/main/images/docker-stacks-foundation/Dockerfile

**Describe the solution you'd like**

- How to create a *feedstock* for conda-forge, which builds for Win/Mac/Linux: https://github.com/conda-forge/staged-recipes/tree/main#12-my-pull-request-passes-all-checks-but-hasnt-received-any-attention-how-do-i-call-attention-to-my-pr--what-is-the-customary-amount-of-time-to-wait
- @conda-forge/help-c-cpp

**Describe alternatives you've considered**
- Install the .tar.gz with another custom script, or a playbook without a package
- Build an RPM package for dnf e.g. with COPR and/or OBS Open Build Service, which builds deb and aur packages, too]

**Additional context**
- ostree (rpm-ostree) requires unlocking the /usr *overlay* before CMMI to /usr/local; packages that can be installed atop the (ostree native container) base image on upgrade or *rebase* are easier with rpm-ostree distros
