graphics/opencv: Fix JAVA option and correct Apache Ant usage

JAVA option did not work because the actual build knob was wrong.
Especially, on a system where devel/apache-ant was installed, ant and
java binaries were automatically detected and enabled even if the JAVA
option was disabled.  While I am here, fix Apache Ant usage by setteing
JAVACMD variable.  Without it, it may pick up java binary from JRE via
javavm(1) from java/javavmwrapper.  If ant script is used with java from
JRE, build fails because it cannot find jar.

Introduce devel/onetbb and mark devel/tbb as legacy

Intel oneAPI tbb 2021.1 (onetbb) has been released[1][2] and has deprecated
several interfaces over tbb 2020, breaking most dependent ports.

Old tbb 2020 will be kept for a certain time to allow transition but will be
removed in a near future as it CONFLICTS with devel/onetbb. New ports should
now use devel/onetbb instead of devel/tbb.

We tried to move a maximum number of dependent ports to devel/onetbb (or
disable dependency when not possible), but some of them still remain stuck
to devel/tbb. Remaining ones have not been identified as major dependencies
themselves and will be fixed as soon as updates are available from upstream.

graphics/opencv: update to 4.5.1 -- and make port more easily maintainable

This is a major upgrade from 3.x to 4.x.

Changelog from versions 3.4.1--4.5.1 can be found here:
    https://github.com/opencv/opencv/wiki/ChangeLog

Note: this has explicitely not been added as a new graphics/opencv4 port, but
replaces the
      previous graphics/opencv[3] port. Again, to improve maintainability by not
giving ports
      the option to pick the "wrong one" - this leads however to some abandoned
ports being
      broken.

The port has been greatly simplified:
    * graphics/opencv-core which existed to enable ffmpeg to depend on opencv,
and vice versa
      has been removed. ffmpeg no longer can depend on opencv.

Bump PORTREVISION to chase update of multimedia/v4l_compat and libv4l

Update ilmbase and openexr to 2.3.0, rename OpenEXR to openexr.

Release notes: <https://github.com/openexr/openexr/releases/tag/v2.3.0>

Adjust LIB_DEPENDS of all ports that require ilmbase or openexr to chase
the new lower-case spelling of the name, and to omit the version from the
library name to ease future maintenance.

Bump PORTREVISION of all ports that depend on ilmbase or openexr directly,
so that they all get rebuilt on upgrades.

Add patches to graphics/ampasCTL to keep it alive, with (a) ilmbase now
that its Iex::BaseExc class is no longer derived from std::string,
details were given upstream through https://github.com/ampas/CTL/issues/71
and (b) to unwind semicolon/;-lists in cmake that stem from openexr/
ilmbase pkg-config variables.
(Note ampasCTL is unmaintained as FreeBSD port, and upstream,
and I cannot run-time test it.)

Poudriere build tests on 11.2-RELEASE-p1 amd64 of ALL ports depending
directly or indirectly on ilmbase and/or openexr have passed without
regressions.  Thus invoking due diligence, I believe I have done the
equivalent of an -exp run, and do not require approval for the dependency
chases to third-party ports.
