Simpler output for less technical users

I know that `vainfo` is more for debugging and for programmers, but could there possibly be an argument like `--format simple` to instead describe the profile and entrypoints as human-readable names and perhaps in a matrix instead?

For example, The following:
```
VAProfileH264Main : VAEntrypointVLD
VAProfileH264Main : VAEntrypointEncSlice
VAProfileH264Main : VAEntrypointFEI
VAProfileH264Main : VAEntrypointEncSliceLP
VAProfileH264High : VAEntrypointVLD
VAProfileH264High : VAEntrypointEncSlice
VAProfileH264High : VAEntrypointFEI
VAProfileH264High : VAEntrypointEncSliceLP
```
could become:
```
Profile Capabilities
H.264 Main: Decode, Encode, FEI, Low-power Encode
H.264 High: Decode, Encode, FEI, Low-power Encode
```
or:
```
Profile Decode Encode FEI Low-power Encode
H.264 Main: ✓ ✓ ✓ ✓
H.264 High: ✓ ✓ ✓ ✓
```

Start with the vainfo command's existing argument handling and profile/entrypoint output. Define the simple format and human-readable capability names, then verify that the selected output presents each profile and capability clearly in the requested list or matrix form.
