Memory improvements to render_pdfs; better DM pool size defaults

Browse Source 
Make SK_DEFAULT_GLOBAL_DISCARDABLE_MEMORY_POOL_SIZE equal to
skia_resource_cache_mb_limit, if that value is >0 (true for some
low-memory Android devices).

render_pdfs test program uses lazy decoding (and the discardable
memory pool).
