media: tegra: Conditionally disable L4T-specific drivers in embedded Linux builds

This change adds conditional compilation blocks to disable L4T-specific
camera and multimedia drivers when building for embedded Linux platforms.
Key changes include:

- Add ifneq ($(NV_BUILD_SYSTEM_TYPE),embedded-linux) checks in multiple
  Makefiles to exclude L4T-specific components
- Introduce NV_IS_L4T define to conditionally include L4T functionality
- Reorganize header includes to support both L4T and embedded Linux builds
- Conditionally wrap L4T-specific struct members and function calls
- Update module dependencies (cdi_mgr now depends on cdi_dev instead of cdi_pwm)
