platform/x86:dell-laptop: Add knobs to change battery charge settings

The Dell BIOS allows you to set custom charging modes, which is useful
in particular for extending battery life. This adds support for tweaking
those various settings from Linux via sysfs knobs. One might, for
example, have their laptop plugged into power at their desk the vast
majority of the time and choose fairly aggressive battery-saving
settings (eg, only charging once the battery drops below 50% and only
charging up to 80%). When leaving for a trip, it would be more useful
to instead switch to a standard charging mode (top off at 100%, charge
any time power is available). Rebooting into the BIOS to change the
charging mode settings is a hassle.

For the Custom charging type mode, we reuse the common
charge_control_{start,end}_threshold sysfs power_supply entries. The
BIOS also has a bunch of other charging modes (with varying levels of
usefulness), so this also adds a 'charge_type' sysfs entry that maps the
standard values to Dell-specific ones.

This work is based on a patch by Perry Yuan <perry_yuan@dell.com> and
Limonciello Mario <Mario_Limonciello@Dell.com> submitted back in 2020.

charge_types power-supply property output format.
