Simd improvement

[laurentcau]

• Add simd aligned_vec3 (and sse aligned_dvec3 - 2 x xmm)
• Fast packed_vec3 <=> aligned_vec3 and packed_vec4 <=> aligned_vec4 conversion
• Fast aligned_vec3 <=> aligned_vec4 conversion
• Optimized aligned_mat x aligned_mat and aligned_mat x aligned_vec
• Inverse aligned_mat3 simd version (actually slower than ssid on my computer even it has 30% less instruction ?)

Note: I fixed the integer div issue reported there: #1255
I also added a test to check there will be no regression in the future.
For the template issues with GLM_FORCE_NEON, since there is no detail, I can't fix it.
All tests are compiling fine on my side with clang + neon. So that should be something not covered by tests but what ? @dimitre

Tests passed

Considering you didn't receive any answer from the ARM NEON issue after multiple query, I think it's fair to break it and have been for who that matters submit a PR.
