Implement Griffin and Cheetah as first-class GCode flavors in OrcaSlicer, enabling proper support for Ultimaker S3, S5, and S7 printers. Griffin is a Marlin-based dialect that uses structured headers (;START_OF_HEADER / ;END_OF_HEADER), G280 prime blob, and per-extruder metadata. Cheetah is a Griffin variant that replaces Marlin's M205 instantaneous jerk with M215 real jerk control (m/s^3 units).

Changes:

Add gcfGriffin and gcfCheetah to GCodeFlavor enum with is_griffin_flavor() helper
Add Griffin-specific config settings: prime_blob_enable, extruder_prime_pos_x/y/z, machine_heated_build_volume, build_volume_temperature, machine_nozzle_id
Implement structured Griffin header generation (write_griffin_header) with extruder train metadata, build plate/volume temperatures, and print bounds
Add G280 prime blob support gated by prime_blob_enable setting
Add Cheetah M215 jerk control in GCodeWriter and machine envelope
Update GCodeProcessor for Griffin/Cheetah flavor detection and time estimation
Update GUI Tab.cpp for conditional visibility of Griffin-specific settings
Add Ultimaker S3, S5, S7 printer profiles with Griffin flavor
