fa2fc2ab - [clang-doc] Simplify parsing and reading bitcode blocks (#190053)

[clang-doc] Simplify parsing and reading bitcode blocks (#190053) Much of the logic in the readBlock implementation is boilerplate, and is repeated for each implementation/specialization. This will become much worse as we introduce new custom block reading logic as we migrate towards arena allocation. In preparation for that, we're introducing the change in logic now, which should make later refactoring much more straightforward.
