arm/video: Fix shader extension and exception handling

Two main changes in this commit:

1. Replace NVIDIA-specific GL_NV_gpu_shader5 extension with the more widely
   supported GL_EXT_shader_explicit_arithmetic_types_float16 in the scaleforce
   shader. This improves compatibility across different GPU vendors.

2. Refactor ARM32 exception handling:
   - Restructure exception cases for better readability
   - Update exception handling to match current Dynarmic API
   - Fix indentation in switch statement
   - Remove AccessViolation case as it's no longer supported in current API

These changes improve shader compatibility and align the exception handling
with the current Dynarmic implementation.
