report: add reporting fields for Embedding Area start and size

There are new reporting fields for Embedding Area: ea_start and ea_size.

An example of 1m Embedding Area and relevant reporting fields:
raw/~ # pvs -o pv_name,pe_start,ea_start,ea_size
  PV         1st PE  EA start EA size
  /dev/sda     2.00m    1.00m   1.00m
