make the ChiaDialect flags a strong type

[arvidn]

using the bitflags crate.

---

Note

Medium Risk
Broad, cross-cutting API type change touches core interpreter flag plumbing and external bindings; behavior should be equivalent but incorrect flag conversions or combination logic could subtly change execution modes.

Overview
Introduces ClvmFlags (via bitflags) to strongly-type ChiaDialect/Dialect flag handling, replacing ad-hoc u32 bitmask constants and updating all call sites to use contains, union, and empty().

Updates public exports to expose ClvmFlags and MEMPOOL_MODE (now a ClvmFlags value), adds ChiaDialect: Default, and includes a unit test to ensure flag bit values don’t overlap.

Python bindings continue to accept u32 flags but now convert via ClvmFlags::from_bits_truncate, and module-level flag constants are exported as bits() values; benchmarks/fuzz/tools are updated accordingly.
