[clangd] Encode Line/Column as a 32-bits integer.
Summary:
This would buy us more memory. Using a 32-bits integer is enough for
most human-readable source code (up to 4M lines and 4K columns).
Previsouly, we used 8 bytes for a position, now 4 bytes, it would save
us 8 bytes for each Ref and each Symbol instance.
For LLVM-project binary index file, we save ~13% memory.
