[polly] Port polly tests to use NPM (#90632)
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. Additionally, the lit
substitution %loadPolly is replaced by the substitution of what
was %loadNPMPolly and %loadNPMPolly is removed.
