RP.160: Enable ML LiveView overlay

[coon42]

This PR adds the required changes to enable ML liveview overlays for EOS RP.160. As autoexec.bin got bigger, ML_RESERVED_MEM has been increased and RESTARTSTART value is adjusted so it fits into RAM again.

Additionally:

• EVF_STATE state object address was added and invalid addresses were removed from internals.h
• SRM is disabled for now as it is not stable / not implemented properly yet.
• XCM is enabled
• finally FEATURE_GLOBAL_DRAW + CONFIG_LIVEVIEW + CONFIG_STATE_OBJECT_HOOKS is enabled to display ML overlay in liveview

Working Things:

• Clock is displayed properly
• Image Quality setting is displayed properly for all possible permutations of RAW/CRAW/L/l/M/m/S1/s1/S2
• Focal length is displayed properly when zooming in and out (tested over the full range with a RF24-240 lens)
• IS (Image Stabilization) is displayed properly. In B (Bulb) mode, it is displayed in cyan color.
• AF (Auto Focus) and MF (Manual Focus) are displayed properly
• Alo (Automatic Light Optimizer) is displayed properly for all possible settings: low = alo, Standard = Alo, High = ALO
• HTP (Highest Tone Priority) is displayed when set to D+ or D+2.
• Battery level is correct for all three battery levels RP provides: Full (White with all bars), Half Full (Yellow) Empty (Red).

(Probably) Not workig Things: - Alo (Automatic Light Optimizer?) is always displayed (not sure how this works yet)

• Most dial modes are displayed properly except Fv + SCN + Movie Mode are displayed as ?
• Aparture value is wrong (Always displays f5.6 or no value at all)
• ISO value is wrong (Always displayed as AUTO)

Added to #30

Aparture value is wrong (Always displays f5.6 or no value at all) ISO value is wrong (Always displayed as AUTO)

Expected, already in #30. It is also true for Tv (shutter speed).

Alo (Automatic Light Optimizer?) is always displayed (not sure how this works yet)

cfn.c in platform dir should handle that (copy content from e.g. R). All D678 so far use generic ALO/HTP handlers.

Copied cfn.c from R.180 and now it is displayed properly. However:

HTP (Highest Tone Priority) is displayed when set to D+ or D+2.

Maybe we should follow the convention of Alo here and display Htp for D+ and HTP for D+2 instead here?
