We need to create a `mremap` wrapper for linux targets, see https://man7.org/linux/man-pages/man2/mremap.2.html.
This requires:
- implement the entrypoint header similar to `libc/src/sys/mman/mmap.h`
- modify `libc/src/sys/mman/CMakeLists.txt` accordingly
- implement the entrypoint similar to `libc/src/sys/mman/linux/mmap.cpp`
- modify `libc/src/sys/mman/linux/CMakeLists.txt` accordingly
- add in the header spec
- modify `functions` section in `libc/newhdrgen/yaml/sys/mman.yaml`
- modify `SysMMan` section in `libc/spec/linux.td`
- add in test
- similar to `libc/test/src/sys/mman/linux/mmap_test.cpp`
- modify `libc/test/src/sys/mman/linux/CMakeLists.txt` accordingly
