Applications with support for Internal Tooling

[coolbreeze413]

A set of 6 applications with built-in support for internal tooling as well as symbiflow, adapted from existing qf_apps applications.

• qorc_helloworldfpga : fpga standalone, symbiflow
• qorc_helloworldfpga_au : fpga standalone, aurora
• qorc_helloworldfpga_mx : fpga standalone, matrixide
• qorc_advancedfpga : m4+fpga, symbiflow
• qorc_advancedfpga_au : m4+fpga, aurora
• qorc_advancedfpga_mx : m4+fpga, matrixide

changes from original qf_apps on which they are based on:

• remove fpga build steps from inside the GCC_Project/Makefile, this one will only build m4 code now
• added separate Makefile for fpga
• added top-level Makefile for each project, uses GCC_Project/Makefile for m4 build, fpga/Makefile for fpga build, and adds load with debugger, flash to board targets to make usage simple, and in line with industry conventions
• also adds VS Code support out of the box for build/load-with-debugger/flash as well as Step Debugging.
