45d81dceed Everywhere: Replace ElfW(type) macro usage with Elf_type
This works around a `clang-format-17` bug which caused certain usages to
be misformatted and fail to compile.

Fixes #8315

9d6372ff07 Kernel: Consolidate finding the ELF stack size with validation
Previously, we started parsing the ELF file again in a completely
different place, and without the partial mapping that we do while
validating.

Instead of doing manual parsing in two places, just capture the
requested stack size right after we validated it.

79adeb626b LibC+LibELF: Move ELF definitions from LibC to LibELF
This is needed to avoid including LibC headers in Lagom builds.
Unfortunately, we cannot rely on the build machine to provide a
fully POSIX-compatible ELF header for Lagom builds, so we have to
use our own.

c87557e9c1 Kernel+Libraries: Don't include limits.h from LibELF/Validation.h
The fallout of this is that Kernel/Syscalls/execve.cpp doesn't have
access to ARG_MAX anymore, so move that definition to Kernel/API as well

7d667b9f69 LibELF: Remove unused m_program_interpreter member from DynamicLoader
While profiling I realized that this member is unused, so the
StringBuilder and String allocation are completely un-necessary.

3e959618c3 LibELF: Use StringBuilders instead of Strings for the interpreter path
This is required for the Kernel's usage of LibELF, since Strings do not
expose allocation failure.

1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

6cb28ecee8 LibC+LibELF: Implement support for the dl_iterate_phdr helper
This helper is used by libgcc_s to figure out where the .eh_frame sections
are located for all loaded shared objects.

67cda61b7f Libraries: Add missing headers
A C++ source file containing just
    #include <LibFoo/Bar.h>
should always compile cleanly.

This patch adds missing header inclusions that could have caused weird error
messages if they were used in a different context. Also, this confused QtCreator.
