Fixes#38764, update `7zip` to 24.06.
No feature needs to be tested, the usage test passed on
`x64-windows`(header files found):
```
7zip provides CMake targets:
# this is heuristically generated, and may not be correct
find_package(7zip CONFIG REQUIRED)
target_link_libraries(main PRIVATE 7zip::7zip)
```
* Extract vcpkg_extract_archive from vcpkg_find_acquire_program.
* Extract vcpkg_download_sourceforge from vcpkg_from_sourceforge.
This allows vcpkg_find_acquire_program to download from SourceForge without needing to temporarily change _VCPKG_EDITABLE.
* Use whether a URI is known for an entity to decide whether to downloads it rather than checking a separate supported_on_unix boolean.
* Add unparsed arguments check to vcpkg_extract_archive
