Implement `-id` option for install-name-tool. Differences from cctool's
behavior:
- 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).
Test plan:
1. make check-all
2. verify that a binary copied via llvm-objcopy now correctly works on iOS.

keeps them for --discard-all operation. Match their behaviour for

The header magic value is held in the native endianness, so the method used in
cc0ec3fdb9d. Use MachOReader / MachOWriter's existing endianness tests instead.
Use shift/mask operations to access r_symbolnum rather than relying on
MachO::relocation_info. This should fix the big-endian bot failures that were
caused by 386f1c114d5.
It can be used to avoid passing the begin and end of a range.
This makes the code shorter and it is consistent with another
wrappers we already have.

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.
Only consider isUndefinedSymbol() when the symbol is not local. This
fixes an assert failure when copying the symbol table, if a n_type=0x20
symbol is followed by a n_type=0x64 symbol.
