X Title: [without findfont diff] Parsing all families in font_manager by aitikgupta · Pull Request #20549 · matplotlib/matplotlib

Description: PR Summary Short Note: This is a newer and more dynamic approach than #20496, which changed findfont's API, thus breaking a lot of backends. A much more flexible approach would be to gradually move the different backends to find_fontsprop instead of findfont, since the new function is built over the existing API and acts as a middleware. Quoting previous PR: This is the beginning of migrating from Matplotlib's "Font-First" approach to a "Text-First" approach. The very first step is to parse all families in font manager. Previously, we only parsed families until we find a font file, and the rest of the backends are accustomed to just a single font file (which needs changing) OrderedDict would contain fonts defined by font.family which are present on the system but also append "fallback fonts" in the end. (which is triggered if a certain font family is not found in the system)## PR Checklist Has pytest style unit tests (and pytest passes). Is Flake 8 compliant (run flake8 on changed files to check). New features are documented, with examples if plot related. Documentation is sphinx and numpydoc compliant (the docs should build without error). Conforms to Matplotlib style conventions (install flake8-docstrings and run flake8 --docstring-convention=all). New features have an entry in doc/users/next_whats_new/ (follow instructions in README.rst there). API changes documented in doc/api/next_api_changes/ (follow instructions in README.rst there).
