feat(profiles): enable cooling filter on H2D, H2D Pro, and H2S

Declare support_cooling_filter=1 on the three profiles (0.2/0.6/0.8
variants inherit from 0.4) and insert the cooling-filter conditional
into the H2D and H2S machine start g-code, inside the low-chamber-temp
airduct branch:

  {if(cooling_filter_enabled)} M145.2 P0 F0 {else} M145.2 P0 F1 {endif}

H2D Pro intentionally gets no g-code edit: its duct firmware takes the
filter mode over the device channel only, so the flag merely enables
the toggle.

Impact on existing users at default settings: H2D/H2S start g-code gains
exactly one line (M145.2 P0 F1, filter off) in the cool-chamber branch;
nothing is removed or reordered. The existing support_air_filtration=1
overrides are deliberately kept so exhaust-fan behavior for ABS-class
filaments is unchanged, even though the machine-tab row is hidden while
the cooling-filter toggle is shown.
