Remove validation bits

Discard invalid properties from json decode. JSON output should only
contain valid properties. This saves time in preventing post
processing of output for valid fields.

Ensure round trip validity with validation bits removed and required
properties populated.

Fix bugs in json decode.

Overhaul unit tests to use valijson. Add tests with static examples
to validate against schema. Use and nlohmann for better schema
validation over intrinsic libcper validation.

Example json output before:
{
"ValidationBits": {
"LevelValid": false,
"CorrectedValid": true
},
"Level": 1,
"Corrected": true
}

After:
{
"Corrected": true
}

clang-format: re-format for clang-19

clang-format-19 isn't compatible with the clang-format-18 output, so we
need to reformat the code with the latest version. A few parameters
in clang-tidy have been deprecated, so adjust the style file
accordingly.

See Ie2f6eb3b043f2d655c9df806815afd7971fd0947 for updated style.
See I88192b41ab7a95599a90915013579608af7bc56f for clang-19 enablement.

Unflatten edk includes

Installing the edk headers into a folder requires us to do odd things
with imports, and either include headers with "..", or otherwise get the
include directories lined up.

Move the contents of edk/*.c/h up a level, and just simplify the include
structure. This is done to fix the immediate change of the prior patch
and make this build again. Happy to discuss other options.

Adjust strncpy sizes

When building under bitbake with the latest openbmc, we get compile
warnings such as these:

```

| 67 | strncpy(section_cper->Signature,
```

Using `strncpy` on its own is unsafe because a string too long will
end up in the destination buffer without NUL termination. Adjust
the strncpy to be one shorter than the buffer and force the trailing
byte to be a NUL.

Repeat this pattern for all `strncpy` calls.
