Cleanup LLVMDebugInfoCodeView headers

Major user-facing changes:

Many headers in llvm/DebugInfo/CodeView no longer include
llvm/Support/BinaryStreamReader.h or llvm/Support/BinaryStreamWriter.h,
those headers may need to be included manually.

Several headers in llvm/DebugInfo/CodeView no longer include
llvm/DebugInfo/CodeView/EnumTables.h or llvm/DebugInfo/CodeView/CodeView.h,
those headers may need to be included manually.

Some statistics:
$ clang++ -E  -Iinclude -I../llvm/include ../llvm/lib/DebugInfo/CodeView/*.cpp -std=c++14 -fno-rtti -fno-exceptions | wc -l
after:  2794466
before: 2832765
