Allow installing pip dependencies from source

[mppf]

This PR includes changes that were in the Homebrew 1.25.1 release as patches to support building the Python pip dependencies from source.

• Work around problems building chpl-venv from source i.e. with pip arguments --no-binary :all: by first installing some chpldoc dependencies into the venv (since they are also build-time dependencies when building from source). Note that building the Python dependencies from source was suggested by Homebrew maintainers in chapel 1.25.1 Homebrew/homebrew-core#91257 (comment) . After this PR, the way to build the pip dependencies is by running e.g. make CHPL_PIP_FROM_SOURCE=1 test-venv (vs CHPL_PIP_INSTALL_PARAMS=--no-binary :all: which was used for the 1.25.1 Homebrew formula).
• Additionally with the above, split chpldoc dependencies into 3 files, so that some can be installed before others, to work as build time dependencies. These 3 files include the version upgrades from Update packages relied upon by chpldoc for Python 3.10 compatibility #18894 (Sphinx from 4.0.2 to 4.3.2; sphinxcontrib-chapeldomain from 0.0.20 to 0.0.21; breathe from 4.30.0 to 4.31.0) as well as upgrading sphinx-rtd-theme from 0.5.2 to 1.0.0 to address problems with building from source.
• Adjusts a test .good file for a trivial difference in output with the sphinx-rtd-theme version change.
• Adjusts another test to avoid platform-specific errors in .good file

Future work:

• add automated testing that make CHPL_PIP_FROM_SOURCE=1 test-venv functions

• check test/chpldoc passes

I think it would probably be good to add a job that makes the module docs by building from source, but it's okay for that to not happen as part of this PR
