fix: properly resolve component dependencies

There is currently a bug in the __build_resolve_and_add_req function in
tools/cmake/build.cmake where the check for registered component
requirements is incorrectly applied to the component itself rather than
its dependencies. This issue likely originated from a typo, using
component_target instead of _component_target. To prevent further
confusion, _component_target has been renamed to _req_target.

Fixing this revealed multiple incorrect dependencies for the Linux
target, which have now been resolved by explicitly specifying the
dependencies for the Linux target.

Closes https://github.com/espressif/esp-idf/issues/13447
