Simplify niosv sim

Existing Sample Changes

Description

An RTL expert advised removing sim:/ from the following lines of code in wave.do:

https://github.com/oneapi-src/oneAPI-samples/blob/2ed1542de0245e426e3ba1fef81afa66209f3070/DirectProgramming/C%2B%2BSYCL_FPGA/ReferenceDesigns/niosv/simulation_files/wave.do#L1-L3

add wave -group "Nios V" -radix hexadecimal -position insertpoint sim:/pd_system_tb/pd_system_inst/nios/*

add wave -group "Code & Data RAM" -radix hexadecimal -position insertpoint sim:/pd_system_tb/pd_system_inst/code_data_ram/*

add wave -group "Accelerator" -radix hexadecimal -position insertpoint sim:/pd_system_tb/pd_system_inst/simple_dma_accelerator/*

I also combined some of the .gitignore files and made a small readme change. None of these affected the source code that is tested, but I ran a regtest as a sanity check:
