feat(core): Add configurable IScopesStorageFactory to SentryOptions (#5199)

* feat(core): Add configurable IScopesStorageFactory to SentryOptions

Allow users to provide a custom IScopesStorage factory via
SentryOptions.setScopesStorageFactory(). When set, the custom factory
takes precedence over the default auto-detection logic.

Fixes #5193

* Revert "ref(core): Have ScopesStorageFactory implement IScopesStorageFactory"

This reverts commit a0d77eb80af274e5fe6a7412bc3b6547f520c2f3.

* feat(core): Pass SentryOptions to IScopesStorageFactory.create()

SPI-discovered factory implementations are instantiated via ServiceLoader
with no-arg constructors, so they need access to options like logger and
DSN at creation time. Change the interface method signature to accept
SentryOptions as a parameter.
