This moves the `reportUniqueWarning` method to the base class.
My motivation is the following:
I've experimented with replacing `reportWarning` calls with `reportUniqueWarning`
in ELF dumper. I've found that for example for removing them from `DynRegionInfo` helper
class, it is worth to pass a dumper instance to it (to be able to call dumper()->reportUniqueWarning()).
The problem was that `ELFDumper<ELFT>` is a template class. I had to make `DynRegionInfo` to be templated
and do lots of minor changes everywhere what did not look reasonable/nice.
At the same time I guess one day other dumpers like COFF/MachO/Wasm etc might want to
start using `reportUniqueWarning` API too. Then it looks reasonable to move the logic to the
base class.
With that the problem of passing the dumper instance will be gone.

We have Error.cpp/.h which contains some code for working with error codes.
In fact we use Error/Expected<> almost everywhere already and we can get rid
of these files.
Note: a few places in the code used readobj specific error codes,
e.g. `return readobj_error::unknown_symbol`. But these codes are never really used,
i.e. the code checks the fact of a success/error call only.
So I've changes them to `return inconvertibleErrorCode()` for now.
It seems that these places probably should be converted to use `Error`/`Expected<>`.

We have a few helper functions like the following:
```
std::error_code create*Dumper(...)
```
In fact we do not need or want to use `std::error_code` and the code
can be simpler if we just return `std::unique_ptr<ObjDumper>`.
This patch does this change and refines the signature of `createDumper`
as well.

SUMMARY:
in the xcoff, if the number of relocation entries or line number entries is
overflow(large than or equal 65535) , there will be overflow section for it.
The interpret of overflow section is different with generic section header,
the patch implement parsing the overflow section.

Summary:
According the the XCOFF document,
If
Then
XTY_SD
x_scnlen contains the csect length.
XTY_LD
x_scnlen contains the symbol table index of the containing csect.
XTY_CM
x_scnlen contains the csect length.
XTY_ER
x_scnlen contains 0.
Change the SectionLen member name to SectionOrLength is more reasonable.

Adds a readobj dumper for 32-bit and 64-bit section header tables, and extend
support for the file-header dumping to include 64-bit object files. Also
refactors the binary file parsing to be done in a helper function in an attempt
to cleanup error handeling.

Summary:
This patch implement parsing symbol table for xcoffobjfile and
output as yaml format. Parsing auxiliary entries of a symbol
will be in a separate patch.
The XCOFF object file (aix_xcoff.o) used in the test comes from

int main()

Patch adds support for dumping of file headers with llvm-readobj. XCOFF
object files are added to test dumping a well formed file, and dumping
both negative timestamps and negative symbol counts, both of which are
allowed in the XCOFF definition.
