Add support for new load commands added by Apple to the MACH-O file format.
bfd * mach-o.h: Add new enums for BFD_MACH_O_PLATFORM_MACOS,
BFD_MACH_O_PLATFORM_IOS, BFD_MACH_O_PLATFORM_TVOS,
BFD_MACH_O_PLATFORM_WATCHOS, BFD_MACH_O_PLATFORM_BRIDGEOS,
BFD_MACH_O_TOOL_CLANG, BFD_MACH_O_TOOL_SWIFT, BFD_MACH_O_TOOL_LD.
(struct bfd_mach_o_note_command): New.
(struct bfd_mach_o_build_version_tool): New.
(struct bfd_mach_o_build_version_command): New.
(bfd_mach_o_read_version_min): Don't split version into
a few fields. Rename reserved to sdk.
* mach-o.c (bfd_mach_o_read_version_min): Don't split version into a
few fields. Rename reserved to sdk.
(bfd_mach_o_read_command): Handle LC_VERSION_MIN_TVOS, LC_NOTE,
LC_BUILD_VERSION.
(bfd_mach_o_read_note): New.
(bfd_mach_o_read_build_version): New.
PR 23728
binutils* od-macho.c (printf_version): New.
(dump_load_command): Use it to print version. Print sdk version. Print
version info for watchOS and tvOS. Print LC_NOTE, LC_BUILD_VERSION.
