mb/google/bluey: Enable dynamic SoC calculation and log battery level

Browse source 
Enable EC_GOOGLE_CHROMEEC_BATTERY_SOC_DYNAMIC for the Quenbi and Quartz
models. These Qualcomm-based boards require State of Charge (SoC) to be
calculated from dynamic battery metrics because the standard charge
state command is restricted during certain active power states.

Additionally, add platform_dump_battery_soc_information() to romstage
to log the battery percentage early in the boot process. This helps
with debugging power-related issues during the early boot sequence
when serial console is enabled.

Details:
- Select EC_GOOGLE_CHROMEEC_BATTERY_SOC_DYNAMIC for Quenbi and Quartz.
- Call the SoC dump in platform_romstage_main() if CONSOLE_SERIAL is on.

BUG=none
TEST=Boot Quenbi/Quartz and verify "Battery state-of-charge X" appears
in the romstage serial console logs.
