Subrata Banik 8cd9454d00 lib: Add support for text rendering on splash screen ... Introduce FRAMEBUFFER_SPLASH_TEXT to allow rendering status messages directly into the linear framebuffer. This enables displaying dynamic information, such as battery levels or system status, during the bootsplash stage without requiring complex graphics libraries. Changes: - Add Kconfig option to toggle framebuffer text support. - User to call `render_text_to_framebuffer` to display the text message. - Include render_text.c in ramstage build when FRAMEBUFFER_SPLASH_TEXT is enabled. - Create 24x32 font table entry using GoogleSansFlex_24pt-Medium.ttf. TEST=Able to build google/fatcat.
