feat(ctrace): preserve DWT address offset widths

[thorstendb-ARM]

Summary

Preserve the original 1-, 2-, or 4-byte width of DWT Data Trace Address packets.

Changes

• accept 1-, 2-, and 4-byte DWT address-offset payloads
• retain the raw value together with its encoded width
• keep the CSV column name offset and format values using their original width
• encode CTF offsets as compact none/u8/u16/u32 variants
• keep offset values available as numeric scalars in Trace Compass
• encode optional PCs without reserving four bytes when absent
• add decoder, CSV, CTF metadata, encoder, and Trace Compass XML tests

Examples:

• 1 byte: 0x58
• 2 bytes: 0x7858
• 4 bytes: 0x20007858

This intentionally preserves the address fragment received from the trace stream. It does not reconstruct an address using DWT_COMP.

Validation

• Release unit tests passed
• Release integration tests passed
• Debug/coverage unit and integration tests passed
• Generated CTF metadata and streams were successfully read with Babeltrace
