[clang][AST] Support AST files larger than 512M
Summary:
Clang uses 32-bit integers for storing bit offsets from the beginning of
the file that results in 512M limit on AST file. This diff replaces
absolute offsets with relative offsets from the beginning of
corresponding data structure when it is possible. And uses 64-bit
offsets for DeclOffests and TypeOffssts because these coder AST
section may easily exceeds 512M alone.
This diff breaks AST file format compatibility so VERSION_MAJOR bumped.
Test Plan:
Existing clang AST serialization tests
Tested on clangd with ~700M and ~900M preamble files
