tdf#50613 add support to load charts asynchronously
Generating primitives for chart visualisation can be moved to a paralell executed task that loads the chart, thus speeding up initial visualization. This is not possible for e.g. PDF or print targets, only for edit visualization. On fallback, the replacement images of the charts are used which are metafiles and have less quality as primitives, but load quicker. Change-Id: I68caa9e1bec50832bce535b5f54633d53cdef037
