kernel.bbclass: Add task to export kernel configuration to SPDX

Browse Source 
Introduce a new bitbake task do_create_kernel_config_spdx that extracts
the kernel configuration from ${B}/.config and exports it into the
recipe's SPDX document as a separate build_Build object.

The kernel config parameters are stored as SPDX DictionaryEntry objects
and linked to the main kernel build using an ancestorOf relationship.

This enables the kernel build's configuration to be explicitly captured
in the SPDX document for compliance, auditing, and reproducibility.

The task is gated by SPDX_INCLUDE_KERNEL_CONFIG (default = "0").
