pw_build: Update pw_linker_script docs
Document the fact that you can simply add pw_linker_script to the deps
of a cc_binary.
Also, use cc_binary (the native Bazel rule) instead of pw_cc_binary (our
custom wrapper), to make it clear that this doesn't rely on any special
handling in the binary rule.
