This helps to detect and report parsing errors better.
The patch follows the ideas of LLDB's patches D59370 and D59381.
It adds tests for valid and some invalid cases. More checks and
tests to come. Note that the patch fixes validation of the Length
field because the value does not include the field itself.
The existing users are updated to show the error messages.

I am using it in https://reviews.llvm.org/D69399.
This change changes how obj2yaml dumps arrays of `llvm::yaml::Hex8/llvm::yaml::Hex16/llvm::yaml::Hex32`
from:
```
PayloadBytes:
- 0x01
- 0x02
...
```
To
```
PayloadBytes: [ 0x01, 0x02, ... ]
```
The latter way is shorter and looks better for arrays.

In my refactoring I introduced a bug where we were using the reference size instead of the offset size for DW_FORM_strp and similar forms.
This patch resolves the error and adds a test case testing all the DWARF forms for DWARF2 AddrSize 8. There is similar coverage already in the DWARFDebugInfoTest sources that covers the parser. Once I migrate the DWARFGenerator APIs to be built on the YAML tools they will be fully covered under the same tests.
