Add support for CUDA architecture family codes (#27278)

This change extends CUDA architecture handling to support
family-specific codes (suffix 'f') introduced in CUDA 12.9, aligning
with updates made to Triton Inference Server repositories (backend and
onnxruntime_backend).

Changes:
1. Added CUDAARCHS environment variable support (standard CMake
variable)
   - Allows users to override architecture list via environment variable
   - Takes precedence when CMAKE_CUDA_ARCHITECTURES is not set

2. Extended regex patterns to recognize family code suffix 'f'
- Supports codes like 100f, 110f, 120f for CC 10.x, 11.x, 12.x families
   - Preserves 'f' suffix during parsing phase

3. Updated normalization logic to handle family codes
- Family codes (ending with 'f') preserved without adding -real suffix
   - Traditional codes continue to receive -real or -a-real suffixes
   - Architecture-specific codes (with 'a') remain unchanged

4. Extended architecture support lists
   - Added SM 110 to ARCHITECTURES_WITH_KERNELS
   - Added SM 110 to ARCHITECTURES_WITH_ACCEL

Family-specific codes (introduced in CUDA 12.9/Blackwell) enable forward
compatibility within a GPU family. For example, 100f runs on CC 10.0,
10.3, and future 10.x devices, using features common across the family.

Usage examples:
- CUDAARCHS="75;80;90;100f;110f;120f" cmake ..
- cmake -DCMAKE_CUDA_ARCHITECTURES="75-real;80-real;90-real;100f;120f"
..
- python build.py --cmake_extra_defines
CMAKE_CUDA_ARCHITECTURES="100f;110f"

The implementation supports mixed formats in the same list:
- Traditional: 75-real, 80-real, 90-real
- Architecture-specific: 90a-real (CC 9.0 only)
- Family-specific: 100f, 110f, 120f (entire family)

Note: Current defaults still use bare numbers (75;80;90;100;120) which
normalize to architecture-specific codes with 'a' suffix. Users who want
family-specific behavior should explicitly use the 'f' suffix via
CUDAARCHS environment variable or CMAKE_CUDA_ARCHITECTURES.
