The few options are niche. They solved a problem which was traditionally solved
with more shell commands (`llvm-readelf -n` fetches the Build ID. Then
`ln` is used to hard link the file to a directory derived from the Build ID.)
Due to limitation, they are no longer used by Fuchsia and they don't appear to
be used elsewhere (checked with Google Search and Debian Code Search). So delete
them without a transition period.

Implement `-id` option for install-name-tool. Differences from cctool's

- Does **NOT** throw an error if multiple -id options are specified.
Instead, picks the last one.

This diff addresses the old TODO in MachOObjcopy.cpp and
correctly sets the page size used for alignment of segments.
In particular, now llvm-objcopy's output is consistent
with the input (the alignment of vmsize doesn't change).

1. make check-all
2. verify that a binary copied via llvm-objcopy now correctly works on iOS.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Summary:
This patch implements copying some load commands that appear in executables/shared libraries such as the indirect symbol table.
I don't add tests intentionally because this patch is incomplete: we need a layout algorithm for executables/shared libraries. I'll submit it as a separate patch with tests.
