microdroid: Add kernel image variant that supports UEFI

Add new microdroid Soong target with EFI support - use VM Capability
'supports_uefi_boot'. Use microdroid GKI Android 15-6.6 kernel image.

This CL is used to enable testing booting of the guest kernel in pvmfw
via EFI stub.

Test: m microdroid_gki-android15-6.6_kernel_signed_supports_uefi_boot
