feat(ivy): support pipe compilation from local metadata (#24703)

This updates the r3_pipe_compiler to not depend on global analysis,
and to produce ngPipeDef instructions in the same way that the other
compilers do. It's a precursor to JIT and AOT implementations of
@Pipe compilation.

PR Close #24703
