sysutils/edk2: Add bhyve as a new FLAVOR of edk2

Instead of having a separate sysutils/uefi-edk2-bhyve port, add bhyve
as a FLAVOR of sysutils/edk2 and delete sysutils/uefi-edk2-bhyve.

To support existing users who depend on firmware in
/usr/local/share/uefi-firmware create compatibility symlinks.

Update sysutils/bhyve-firmware to depend on edk2@bhyve.

o sysutils/uefi-edk2-bhyve-csm is no longer a slave port, since it
  continues to use the GH/freebsd/uefi-edk2 repo.
o sysutils/uefi-edk2-bhyve-devel is no longer required, so delete it.
o Update the port Makefiles to follow the style in sysutils/edk2.

Back port r564778 | gerald | 2021-02-09 from uefi-edk2-bhyve-devel to
uefi-edk2-bhyve:

  Convert uefi-edk2-bhyve-devel to leverage the new "build" argument to
  USE_GCC, thus replacing direct manipulation of RUN_DEPENDS by the much
  simpler, declarative USE_GCC=yes:build.

BaseTools: Add missing Elf relocation type for LTO build

Add support to convert missing Elf relocation types
(R_X86_64_PLT32, R_X86_64_GOTPCREL, R_X86_64_REX_GOTPCRELX)
to PeCoff, which are required by LTO image.

These changes are necessary to unbreak sysutils/uefi-edk2-bhyve on
FreeBSD after the update of devel/binutils to version 2.31.1.

Special thanks to bap@FreeBSD.org to help me debug and find a
solution for this issue.

sysutils/uefi-edk2-bhyve: Remove GCC run dependency

The firmware does not require or link with any of the libraries
provided by GCC, so remove the GCC run dependency.

Due to the lack of an accepted better solution in bsd.gcc.mk to do
this, we use the hack used by other ports like devel/linux-kernel,
sysutils/memtest86+, sysutils/grub2-bhyve, misc/seabios, net/ipxe, ...

Bump PORTREVISION for ports depending on the canonical version of GCC
(via Mk/bsd.default-versions.mk and lang/gcc) which has moved from
GCC 5.4 to GCC 6.4 under most circumstances.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c++11-lib, c++11-lang,
   c++14-lang, c++0x, c11, or gcc-c++11-lib.
