  -----------
  [LLVM][Coverage][Unittest] Fix dangling reference in unittest (#147118)

In loop of `writeAndReadCoverageRegions`, `OutputFunctions[I].Filenames`
references to contents of `Filenames` after returning from
`readCoverageRegions` but `Filenames` will be cleared in next call of
`readCoverageRegions`, causes dangling reference.
The lifetime of the contents of `Filenames` must be equal or longer than
`OutputFunctions[I]`, thus it has been moved into `OutputFunctions[I]`
(typed `OutputFunctionCoverageData`).
