svga: add new GALLIUM_HUD queries

Add new GALLIUM_HUD queries for:
    num-shaders
    num-resources
    num-state-objects
    num-validations
    map-buffer-time
    num-surface-views
    num-resources-mapped
    num-flushes

Most of this patch was originally written by Neha.  Additional clean-ups
and num-flushes counter added by Brian Paul.
