oe-pkgdata-util: new option to provide full info for binary package(s)

New option can be used for displaying full information about binary
package(s), including name, full version, recipe name, recipe full
version and package size.

This information can be useful inside custom buildhistory class
to produce detailed image manifest for further analysis.

List of packages can be specified as command line arguments or can
be read from file (e.g. from existing image manifest).

Warning: In case of image manifest is used as input outside of build
process, be aware that pkgdata might change since the time image
was built.

Output format:
{PKG} [PKGE:]{PKGV}[-{PKGR}] {PN} [PE:]{PV}[-{PR}] {PKGSIZE}
