soc: arm: rpi_pico: Add basic support for binary info feature

Enable embedding binary info to flash.
As a default, information collects from the build configuration.

It can override by the Kconfig configurations, such as

```
CONFIG_RP2_BINARY_INFO_PROGRAM_NAME_OVERRIDE=y
CONFIG_RP2_BINARY_INFO_PROGRAM_NAME="my program name"
```
