When we produce an YAML output, we also print leading zeroes currently.
An output might look like this:
```
- Name: .dynsym
Type: SHT_DYNSYM
Address: 0x0000000000001000
EntSize: 0x0000000000000018
```
There are probably no reason to print leading zeroes.
It just makes harder to read values. This patch stops printing them.
The output becomes like:
```
- Name: .dynsym
Type: SHT_DYNSYM
Address: 0x1000
EntSize: 0x18
```
This affects obj2yaml mostly, but also dsymutil and llvm-xray tools output.

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.

Summary:
Our YAML library's handling of tags isn't perfect, but it is good enough to get rid of the need for the --format argument to yaml2obj. This patch does exactly that.
Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are:
!ELF
!COFF
!mach-o
!fat-mach-o
I have a corresponding patch that is quite large that fixes up all the in-tree test cases.
