Fix Matter Door Lock Operating Mode select entity

[lboue]

Proposed change

Problem: The Door Lock Operating Mode selector was including all 5 operating modes unconditionally, but the Matter specification uses a bitmap attribute (SupportedOperatingModes) to indicate which modes a device actually supports.

Solution: Created a specialized MatterDoorLockOperatingModeSelectEntity class that:

1. Reads the bitmap: Retrieves the SupportedOperatingModes bitmap from the device
2. Extracts enabled bits: Converts the bitmap to bit positions (0-4, representing the 5 operating modes)
3. Filters options dynamically: Only includes modes that the device supports
4. Maintains translation support: Uses the full DOOR_LOCK_OPERATING_MODE_MAP for all possible translations

Key Features:

• ✅ Respects Matter bitmap specification
• ✅ Dynamically updates available modes based on device capabilities
• ✅ Full translation support for all 5 operating modes (Normal, Vacation, Privacy, NoRemoteLockUnlock, Passage)
• ✅ Handles enum to string conversion for user selection
• ✅ Writes correct enum values when options are selected

SupportedOperatingModes Attribute

• This attribute SHALL contain a bitmap with all operating bits of the OperatingMode attribute supported by the lock.
• A bit position set to zero SHALL indicate that the mode is supported. A bit position set to one SHALL indicate that the mode is not supported.
• Any bit that is not yet defined in OperatingModesBitmap SHALL be set to 1.

Pull request overview

This PR fixes a bug where the Matter Door Lock Operating Mode selector was showing all 5 operating modes regardless of device capabilities. The solution implements bitmap-based filtering using the Matter specification's SupportedOperatingModes attribute, where bit=0 indicates a supported mode and bit=1 indicates unsupported.

Key changes:

• Created specialized MatterDoorLockOperatingModeSelectEntity class that reads and interprets the SupportedOperatingModes bitmap
• Changed discovery schema to use MatterMapSelectEntityDescription with bitmap attribute support
• Updated tests to verify bitmap-based filtering and only test with supported operating modes
