Add LLFloaterAbout info (esp. GPU info) to Frame Profile stats dump

With the About info added, `getProfileStatsContext()` need not redundantly add
`"channel"`, `"version"` or `"region"`.

Slightly improve the efficiency of `LlsdToJson()` and `LlsdFromJson()` by
preallocating the known size of the source array or map. (Unfortunately the C++
`LLSD` class offers us no way to preallocate a map.)

In `LLAppViewer::getViewerInfo()`, avoid immediate successive calls to
`gAgent.getRegion()`.
