this change makes df text and bmp text have a common interface.  It also has a
few more small cleanups.

File src/gpu/text/GrAtlasTextBlob.h (right):

src/gpu/text/GrAtlasTextBlob.h:293: // sets the last subrun to use distance
field text
says last but takes an index?

Comment updated.  I think my ultimate goal is to have the blob itself track the
current run, and make the whole notion of runs / subruns basically opaque to the
user of the blob.  We'll see though
