gpt: add qbootctl A/B slot flags as named GPT attributes

[Royyan Zahir (royzah)]

--attributes was parsed only into the bootable (bit 2) and readonly (bit 60) flags, so the qbootctl A/B slot attributes were dropped and never reached the GPT.

Add active / successful / unbootable as named partition options (gen_partition --active / --successful / --unbootable), mapping to the qbootctl A/B attribute bits (gpt-utils.h: 50 / 54 / 55). ptool builds the GPT Attributes from these named flags; no raw attribute value is written.

I reverted the raw value and switched to named flags: --active / --successful / --unbootable mapping to gpt-utils.h bits 50/54/55.

Added the Signed-off-by, thanks.

Dmitry Baryshkov (@lumag) rebased on main and completed the named set: --bootable, --readonly, --priority, --tries-remaining alongside --active/--successful/--unbootable. Every attribute bit is now reachable by name, so --attributes is never required. Kept it working for compatibility, named flags take precedence. Ready for another look.

This is doing inside the legacy .conf format exactly what the YAML rework (#134) stands for - replacing an opaque hex blob with named, typed fields

I have no comments for this particular PR (LGTM), the fundamental question is if we want to keep investing time and prettify existing legacy conf file format

Btw, it also needs a make generate-checksums commit with update checksums (likely every partitions.xml for every board will change (three new attributes per partition))

[Royyan Zahir (royzah)]

Igor Opaniuk (@igoropaniuk) thanks, checksums pushed. only the 31 partitions.xml changed, zero GPT binaries, so no board's actual partition table moves.

on legacy vs YAML, fair question, up to you and Dmitry Baryshkov (@lumag). two things worth knowing: this is also a bug fix, not just nicer names. to_bool() turns 1/yes/true into "true", and ptool.py checks == "true", so a raw value did nothing before.

and whatever #134 lands as, the .conf path sticks around until every board moves, so the flags need to work there anyway.

[Royyan Zahir (royzah)]

Dmitry Baryshkov (@lumag) done, squashed the checksums into the flags commit.

[Royyan Zahir (royzah)]

Rebased on main, checksums regenerated on top of the qcs615-ride layout change, checks green locally. Dmitry Baryshkov (@lumag) PTAL
