epriestley c666cb9f0b Reduce the frequency of DOM scans to rebuild inlines when scrolling revisions
Summary:
Ref T13513. See PHI1734, which raises a concern about the performance of large revisions near the 100-change threshold.

Currently, `getInlines()` is called whenever the scroll position transitions between two changesets, and it performs a relatively complicated DOM scan to lift inlines out of the document.

This shows up as taking a small but nontrivial amount of time in Firefox profiles and should be safely memoizable.

Test Plan:
  - Under Firefox profiling, scrolled through a large revision.
  - Before change: `getInlines()` appeared as the highest-cost thing we're explicitly doing on profiles.
  - After change: `getInlines()` was no longer meaningfully represented on profiles.
  - Created inlines, edited inlines, etc. Didn't identify any broken behavior.
