Lowers the highest recognized shader model from 6.10 back to 6.9 for this new 1.9 release.

Lower the highest recognized shader model from 6.10 to 6.9 so this
release branch only produces up to Shader Model 6.9. Sets
highest_minor = 9 in hctdb_instrhelp.py and regenerates the dependent
sources (DxilConstants.h, DxilShaderModel.h/.cpp, HLSLOptions.td),
dropping all 6.10 target profiles, the SM 6.10 table entries, and
IsSM610Plus. kDxilMinor and the validator version follow at 1.9.

Superseded by #8618, staged from my fork (alsepkow/DirectXShaderCompiler) instead of an upstream topic branch.
