  [LLDB] Fix 64 bit support for CIE and FDE handling in DWARFCallFrameInfo (#158350)

- Introduced a new helper function `IsCIEMarker` to determine if a given
`cie_id` indicates a CIE (Common Information Entry) or FDE (Frame
Description Entry).
- New helper function can now correctly identify both 32-bit and 64-bit
CIE based on the DWARF specifications.
- Updated the `ParseCIE` and `GetFDEIndex` methods to utilize the new
helper function for improved clarity and correctness in identifying CIE
and FDE entries.
- Replaced direct comparisons with `UINT32_MAX` and `UINT64_MAX` with
`std::numeric_limits` for better readability.
