pw_watch: Update target/directory syntax
Since specifying which Ninja targets to build is now just as important
as which directory to build, update pw_watch's command line syntax to

Before
pw watch out#host#docs another/build/dir#stm32f429i
After
pw watch out host docs --build-directory another/build/dir stm32f429i
