The `mips-got-overlapped.test` was introduced in D16968 and its intention is
to check that when there is an empty section at the same address as `.got`,
then we are able to locate `.got` and dump it.
The issue is that this test does not test llvm-readelf and uses a precompiled
object. This path starts using YAML instead and merges
mips-got-overlapped.test to mips-got.test.

We have a `findSectionByName` helper that tries to find a section
by it name. It is used in a few places, but never tested.
I'd like to reuse this helper for a different place.
For this, I've changed it to return Expected<> and now it
doesn't use `unwrapOrErr` anymore. It also now a member of
Dumper class and might report warnings.

This is a follow-up for D83225. This does the following:
1) Adds missing tests for existent errors.
2) Stops using `unwrapOrError` to propagate errors to caller.
(I am trying to get rid of all `unwrapOrErr` calls in the llvm-readelf code).
3) Improves error messages reported slightly.

`MipsGOTParser` is a helper class that is used to dump MIPS GOT and PLT.
There is a problem with it: it might call report_fatal_error() on invalid input.
When this happens, the tool reports a crash:
```
# command stderr:
LLVM ERROR: Cannot find PLTGOT dynamic table tag.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backt
race.
Stack dump:
...
```
Such error were not tested. In this patch I've refactored `MipsGOTParser`:
I've splitted handling of GOT and PLT to separate methods. This allows to propagate
any possible errors to caller and should allow to dump the PLT when something is wrong
with the GOT and vise versa in the future.
I've added tests for each `report_fatal_error()`
and now calling the `reportError` instead. In the future we might want to switch to
reporting warnings, but it requres the additional testing and should
be performed independently.
I've kept `unwrapOrError` calls untouched for now as I'd like to focus on eliminating
`report_fatal_error` calls in this patch only.

This creates the next subfolders in the test directory:
"COFF", "ELF", "MachO", "wasm".
I've also removed platform specific prefixes, like "coff-*".
One unused binary was removed as well: `Inputs/relocs.obj.elf-mips`
