Pull request overview

This PR removes the analog GPIO API surface from Pi4J core and its related mock/test infrastructure, simplifying the provider model to only cover the currently supported digital/PWM/I2C/SPI/Serial IO types.

Changes:

• Removed com.pi4j.io.gpio.analog types/config/builders and eliminated analog entries from IOType, provider registries, and helper creator APIs.
• Removed mock analog providers and test analog provider scaffolding, plus related JPMS exports/uses.
• Performed minor cleanup/consistency edits in digital GPIO Javadocs and platform/provider constant definitions.
