Add Target Energy API & UI for Vehicles Without SoC

[andig]

Fix #2632: the target energy api will only be offered if vehicle does not support SoC

• add charged energy amount api
• mark/identify non-soc vehicles
• add ui

Out of scope:

• add range (SoC diff is shown when capacity is given)
• target charging (won't work!)

UI Changes

• Vehicle with unknown SoC (offline vehicles, guest vehicles) get the ability to specify a kWh based limit
• Limit can be changed in 5 kWh increments (default), 1 kWh for vehicle capacity < 25 kWh, 2 kWh for vehicle capacity < 50 kWh)
• Progressbar shows the progress towards the energy target
• If vehicle capacity is known an estimated SoC diff is shown as extra info (e.g. +22%)
• When kWh based charging is active the "charged/geladen" information is shown at the bottom left and replaces the SoC to create symmetry. "Charged kWh / Target kWh" and "Current SoC / Target SoC".
