mb/google/fatcat: Introduce variant-specific barrel jack presence check

This commit introduces a weak function
`variant_is_barrel_charger_present()` to allow individual Fatcat
variants to specify if they support power-on via a barrel jack.

The default implementation of this function returns `false`,
reflecting the fact that most Chromebook devices within the Fatcat
family primarily use USB-C for power.

The `baseboard_devtree_update()` function is updated to use this
variant-specific check instead of directly calling
`google_chromeec_is_barrel_charger_present()` and checking the board
model. This allows for more flexibility in handling barrel jack
presence across different Fatcat variants.

This change enables specific variants that do support barrel jack
power to override the weak function and return `true`, allowing the
system to behave accordingly (e.g., skipping power optimization when
booting with a barrel charger).

TEST=Able to build and boot google/fatcat.
