Improve module configuration (#661)
DTS modules (device modules) often have a single source file with an empty `struct Module`.
The module's yaml file now allows a `dts-only` boolean to be set, so the source file becomes optional.
`devicetree.yaml` is renamed everywhere to `module.yaml`

ST7121 display controller

Driver for the Sitronix ST7121 MIPI-DSI display panel (sitronix,st7121), driven over ESP-IDF's esp_lcd_st7121 component (DPI/DBI interface, ESP32-P4 and other SOC_MIPI_DSI_SUPPORTED targets only). Owns the MIPI DSI PHY LDO channel and DSI bus directly, so unlike SPI/RGB panels it has no parent bus controller device.

The ST7121 panel's in-cell touch controller is the same chip/protocol as the ST7123's (see st7123-module's sitronix,st7123-touch driver) - boards using this display reuse that driver for touch rather than duplicating it here.
