[ObjCopy] Respect requirements of LC_ENCRYPTION_INFO commands (#120995)
LLD (and other Mach-O linkers) when preparing an encryptable binary make
space to leave all the load commands in an non-encrypted page (see [1])
When using objcopy of a small encryptable binary, the code was not
respecting this fact, and the encryptable segments were not kept beyond
the first page. This was obvious for small or empty binaries.
The changes introduced here keep track if a `LC_ENCRYPTION_INFO` or
`LC_ENCRYPTION_INFO_64` has been seen, and in such case, it adds a full
page of offset in order to leave the load commands in its own page
(similar to what LLD is doing).

[llvm-objcopy] Add support of symbol modification flags for MachO (#120895)
This patch adds support of the following llvm-objcopy flags for MachO:
- `--globalize-symbol`, `--globalize-symbols`,
- `--keep-global-symbol`, `-G`, `--keep-global-symbols`,
- `--localize-symbol`, `-L`, `--localize-symbols`,
- `--skip-symbol`, `--skip-symbols`.
Code in `updateAndRemoveSymbols` for MachO
is kept similar to its version for ELF.
Fixes #120894

[llvm] Use std::nullopt instead of None (NFC)
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

Fix llvm/lib/ObjCopy, llvm/llvm-ifs: c++20 compatibility
Cleanup: avoid referring to `std::vector<T>` members when `T` is incomplete.
This is [not legal](https://timsong-cpp.github.io/cppwp/n4868/vector#overview-4)
according to the C++ standard, and causes build errors in particular in C++20
mode. Fix it by defining the vector's type before using the vector.

[objcopy][NFC] Rename files to avoid clashing of archive members.
libtool uses file names to name members of an static library.
Files, located in different directories and having matching name,
would have the same name inside an archive. This is not a problem
for ld, but may be a problem for ar. This patch renames files
from ObjCopy library to avoid names clashing.
