lib: Add support for different bootsplash types

Browse source 
This commit introduces an enumerated type `bootsplash_type` to
differentiate between various bootsplash logos, such as
`BOOTSPLASH_LOW_BATTERY` and `BOOTSPLASH_CENTER`.

A `bootsplash_list` array is added to map these types to their
corresponding default filenames. A new function,
`bmp_get_logo_filename`, is provided to retrieve the correct logo
filename based on the specified bootsplash type. This function also
handles overriding the `BOOTSPLASH_CENTER` logo name if
`CONFIG(HAVE_CUSTOM_BMP_LOGO)` is enabled.

The `bmp_load_logo` function is updated to utilize the new
`bootsplash_type` and `bmp_get_logo_filename` to dynamically select the
appropriate logo for display. This change streamlines logo management
and improves flexibility for different boot scenarios.

BUG=b:423591644
TEST=Able to build and boot google/fatcat. FW splash screen looks
proper.
