boost - Migrate remaining ports to use the Boost PortGroup

[cjones051073 (Chris Jones)]

I have recently done a bit of work, migrating as many ports as I could using boost to use the boost PG. These are the remaining ports directly using the old boost port

 > port list depends:':boost($|\s)'
aircraft_oap                   @3.0.2          science/aircraft_oap
boost-numpy                    @1.71.0         devel/boost
freeling                       @3.1            textproc/freeling
glob2                          @0.9.4.4        games/glob2
libreoffice                    @7.1.4.2        office/libreoffice
lscsoft-deps                   @20200805       science/lscsoft-deps
openvrml                       @0.18.9         graphics/openvrml
QLColorCode                    @4.1.0          sysutils/QLColorCode
simplevoc-open                 @1.8.0          databases/simplevoc-open
tcpflow                        @1.5.2          net/tcpflow
textmate2                      @2.0.6          editors/textmate2
vcsn                           @2.8            devel/vcsn
wesnoth                        @1.14.13        games/wesnoth

These all (well maybe not the last one which I am not sure on its use) have issues that meant migrating over did not work 'out the box'. e.g. a number use the scons build system and I failed to figure out how to get that to use the isolated boostXYZ ports.

We should try and figure out for each what to do. A number don't build, maybe on all OSes, so perhaps are not used and should be retired.
