Summary:
LogBox tends to take a bit of time to open after tapping a log banner. This is very noticeable on Android where it takes multiple seconds.
When looking at React DevTools, the Stack Frame code can be responsible for two thirds of total LogBox rendering time. With this diff, the time is reduced from about 46ms to 25ms, and the total time spent rendering LogBox is reduced by one third.
This diff makes a few micro-optimizations but primarily it gets rid of an unnecessary View and collapses multiple text components into a single one as they are all rendered the same. Note that this also fixes an issue in the case where a line number may be missing but a column was provided. While I can't think of a case where that would actually happen, previously it would print the column (which could be mistaken for the lineNumber in that case) but now it prints the column only if the line Number is also present.
