Description

CMAKE build types cleaned up in cmakelists

# Build Type Configuration
#
# CMake support for different build types controlling optimization, debugging and profiling:
#
#   - Debug         : No optimizations (`-O0`), includes debug symbols (`-g`).
#   - Release       : Optimized build (`-O3`), removes debug symbols.
#   - RelWithDebInfo: Optimized (`-O2`) but keeps debug symbols (`-g`) for profiling.
#   - Profiling     : Custom build type (defined in this project) that enables:
#                     - CPU profiling via `-pg` (GPROF)
#                     - CUDA profiling via `-lineinfo` (for Nsight Compute)
#
# Selecting a Build Type:
#   - By default, CMake does NOT set a build type for single-config generators.
#   - If no build type is specified, this script defaults to "Release" for performance.
#   - You can explicitly set the build type when configuring CMake:
#
#       cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug      # Debug mode
#       cmake -S . -B build -DCMAKE_BUILD_TYPE=Release    # Release mode
#       cmake -S . -B build -DCMAKE_BUILD_TYPE=Profiling  # Profiling mode 
#       
#       If you don't want to pass in the build type flag, you can edit this file and add...
#               set(CMAKE_BUILD_TYPE "Debug") or whichever build type you want
# -----------------------------------------------------------------------------

Additionally, added a new conditional flag to change the target architecture for cuda compilation.

#CONDITIONAL FLAG to change target architecture for the GPU simulator from the default
#
#You can pass this flag when running cmake from the command line like this, setting TARGET_ARCH \
#       to your desired architecture:                                                            \
#
#cmake -D ENABLE_CUDA=YES -D TARGET_ARCH=70 ..
#
#"YES" / GPU choice only available if CUDA library is installed and the GPU is CUDA capable.
#If no TARGET_ARCH is passed in then it will default to 37 which is the kepler architecture

Quickstart guide, StudentSetup, and codingConventions documentation was updated.
Added support for nvtx profiling tools. The profiling build option will enable this if the nvtx libraries are present.

I think we want this tracked by git; it's used for manual testing and should be kept in sync with the GitHub actions.
