examples: Make gaussian build on all targets
...
Restructure gaussian.rs to follow the pattern used by hex.rs and
connect5.rs.
Remove the 'hexagon' feature gate.

examples: Use HvxVectorPair for precise Gaussian blur arithmetic
...
Update the Gaussian 3x3 blur example to use HvxVectorPair widening
operations. This demonstrates that HvxVectorPair intrinsics now work
correctly with the updated nightly.
- Add #![cfg(target_arch = "hexagon")] crate-level gate

examples: Simplify gaussian.rs with cfg gate
...
Add `#![cfg(target_arch = "hexagon")]`
- Remove redundant #[cfg(target_arch = "hexagon")] from functions
- Simplify import and constant cfg conditions
- Remove non-Hexagon test code branch from main()

examples: Add assertions to gaussian example
...
Replace print statements with assertions that verify the Gaussian 3x3
blur implementation against the Hexagon SDK reference algorithm.
- Port exact SDK Gaussian3x3u8 implementation from:
/opt/Hexagon_SDK/.../Examples/HVX/gaussian/src/gaussian.c
- Verify specific output values [15, 16, 17, 18, 19, 20, 21, 22]
for row 2, cols 1..9 with test pattern ((x + y*7) % 256)
- Assert byte-averaging approximation exactly matches SDK reference
- On Hexagon: verify HVX output matches both scalar approximation
and SDK reference exactly
