Reland sfps enroll improvement feature with feature provider

Prior cl, ag/24720067, was reverted due to platinum failed,
this cl fixes the fails (NPE on UDFPS).

Bug: 288155127
Bug: 305132251
Test: Manually check on Lynx and Felix
Test: atest BiometricsE2eTests:FingerprintEnrollSuccessTest
Test: abtd for platinum, see b/305048300#comment14
Change-Id: I90f4ea14853edf03abd8ffe0b7874894eb2d4f81
