Move unit abbreviation strings into culture-specific resource files (#1210)
Fixes #1126 Refs #1238 A quick draft to move the unit abbreviations into resource files. I also want to move methods for getting culture-specific abbreviations to the individual quantities. This should: - Reduce initialization time by removing the MapGeneratedLocalizations methods (TODO) - Reduce in-memory footprint by only loading a requested culture - Allow formatting to use methods on the quantities themselves - Which should allow for better extensibility as well - Remove the unit abbreviations cache (deprecate) ### TODOs - [ ] Test fallback to invariant culture `export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT='1'` #1238 --------- Co-authored-by: Andreas Gullberg Larsen <andreas.larsen84@gmail.com>
