  Fix silent truncation of inline ASM `srcloc` cookie when going through a `DiagnosticInfoSrcMgr` (#84559)

The size of the inline ASM `srcloc` cookie was changed from 32 bits to
64 bits in [D105491](https://reviews.llvm.org/D105491). However, that
commit only updated the size of the cookie in `DiagnosticInfoInlineAsm`,
meaning that inline ASM diagnostics that are instead represented with a
`DiagnosticInfoSrcMgr` have their cookies truncated to 32 bits. This PR
replaces the remaining uses of `unsigned` to represent the cookie with
`uint64_t`, allowing the cookie to make it all the way to the diagnostic
handler without being truncated.
