Accept both simulator UUIDs and simulator device names in @rules_apple//apple/build_settings:ios_device

[ssarad]

The @rules_apple//apple/build_settings:ios_device build setting was supposed to accept both simulator UUIDs and simulator device names (like "iPhone 15 Pro"), but it only worked with UUIDs. The problem was in apple/internal/ios_rules.bzl where the ios_device value was always passed as simulator_identifier (which expects a UUID) instead of being passed to the appropriate parameter based on its format.

This is particularly nice for companies that require proxy certs in simulators and allows you to reuse pre-loaded simulators with all the certs

Updated the simulator executable registration to:

• Check if ios_device is a UUID or a device name
• Pass it as simulator_identifier if it's a UUID
• Pass it as simulator_device if it's a device name (like "iPhone 15 Pro")
• Fall back to the default ios_simulator_device setting if ios_device is not set
