config_tools/target: generate Software SRAM related info

This patch parsees physical RTCT entries and dump information about pseudo
RAM into the board XML files. A macro named PRE_RTVM_SW_SRAM_BASE_GPA is
added to the generated misc_cfg.h according to recent design changes.

This patch still writes the board XML file manually, following the
convention of the current framework. Using XML-based approach requires a
complete refinement of the current generation process as the root
`acrn-config` node has its own text among adjacent children.
