Update llvm, adjust dependency specs and conflicts (#14561) 
This PR adds a new version of llvm and fixes the dependency specs.

- This package depends on libtinfo in all cases so change the ncurses
  dependency to reflect that
- if +lldb is in the spec but +python is not then do not build the lldb
  python support
- build lldb python support only if +python is in the spec with +lldb
- install the llvm python bindings if +python is in the spec
- install the clang python bindings if +clang and +python are in the spec
- Fixes for conflicts with ~clang
- Fix typo in conflict of compiler-rt and flang
