Georgii Rymar a6436b0b3a [yaml2obj] - Make the 'Machine' key optional.
Currently we have to set 'Machine' to something in our
YAML descriptions. Usually we use 'EM_X86_64' for 64-bit targets
and 'EM_386' for 32-bit targets. At the same time, in fact, in most
cases our tests do not need a machine type and we can use
'EM_NONE'.

This is cleaner, because avoids the need of using a particular machine.

In this patch I've made the 'Machine' key optional (the default value,
when it is not specified is `EM_NONE`) and removed it (where possible)
from yaml2obj, obj2yaml and llvm-readobj tests.

There are few tests left where I decided not to remove it, because
I didn't want to touch CHECK lines or doing anything more complex
than a removing a "Machine: *" line and formatting lines around.

Georgii Rymar 2bca784ab8 [llvm-readobj] - Massive test cases cleanup.
This patch does the following:
1) Starts using YAML macro to reduce the number of YAML documents in tests.
2) Adds `#` before 'RUN'/`CHECK` lines in a few tests where it is missing.
3) Removes unused YAML keys.
4) Starts using `ENTSIZE=<none>` to simplify tests (see D84526).
5) Removes trailing white spaces in a few places.

Georgii Rymar e19628fde5 [llvm-readobj] - Fix crashes and misbehaviors when reading strings from broken string tables.
There are cases when we either might print garbage or crash when
reading strings for dumping dynamic tags.

For example when a string table is not null-terminated or goes past the EOF.
This patch fixes issues mentioned.

Georgii Rymar 7fc599ceb0 [llvm-readobj] - Introduce warnings for cases when unable to read strings from string tables.
Currently we have no dedicated warnings, but we return error message instead of a result.
It is generally not consistent with another warnings we have.

This change was suggested and discussed here:
https://reviews.llvm.org/D77216#1954873

This change refines error messages we report and also I had to update the API
to implement it.

Georgii Rymar e77c149f0e [llvm-readobj] - Refine --needed-libs implementation and add a test.
We have no good test for --needed-libs option.
The one we have as a part of Object/readobj-shared-object.test
is not complete.

In this patch I've did a minor NFC changes to the implementation and
added a test. This allowed to remove this piece from
Object/readobj-shared-object.test
