  [WTF] WTFReportBacktraceWithPrefixAndStackDepth() crashes after 286344 at main

Reviewed by Abrar Rahman Protyasha.

Use `resize()` instead of `reserveInitialCapacity()` here — the latter only expands the backing
memory to the given capacity, but the initial size of the vector is still 0. This caused `subspan`
to crash immediately when attempting to access the subspan starting from `kDefaultFramesToSkip`.
