Even as the NPM has been in use by Polly for a while now, the majority of the tests continue using the LPM passes. This patch ports the tests to use the NPM passes (for example, by replacing a flag such as -polly-detect with -passes=polly-detect following the NPM syntax for specifying passes) with some exceptions for some missing features in the new passes. Relanding #90632.
