Performance Tuning

[ormsbee]

I'm putting this as a placeholder to track a number of performance tuning pull requests that I have open, and make sure they get backported into Sumac properly. This isn't really a product proposal in the traditional sense. Please let me know if I should move this ticket elsewhere.

• perf: cache missing XBlock mappings in load_class XBlock#813
• perf: upgrade XBlock to 5.1.1 for caching unknown tags edx-platform#36151
• feat: create get_course_videos_qset API call edx-val#557
• chore: release 2.9.0 edx-val#559
• perf: reduce ORM queries needed for video quality info edx-platform#36112
• perf: reduce cache queries for StackedConfigurationModel edx-platform#36133
• perf: normalize LMS vs. Studio debug-toolbar settings edx-platform#36134
• perf: request cache get_schedule_for_user edx-when#259 (was merged earlier, but not properly released until recently)
• perf: update edx-when to 2.5.1 to get perf fix edx-platform#36144

@ormsbee - if this is necessary to track as product work this could stay as a product proposal otherwise I'd move to public-engineering
