Fix SPDX headers in all files
I ran the `bin/console spdx --fix` with different strategies for
different files. For most of the core classes, since they've been
drastically rebuilt, I've run it with the `git-blame` strategy, for for
the `src/Validators`, in which the API changed completely but the logic
remains the same, I use the `git-log` strategy.

# TrueVal
- `TrueVal()`
Validates if a value is considered as `true`.
```php
v::trueVal()->assert(true);
// Validation passes successfully
v::trueVal()->assert(1);
// Validation passes successfully
v::trueVal()->assert('1');
// Validation passes successfully
v::trueVal()->assert('true');
// Validation passes successfully
v::trueVal()->assert('on');
// Validation passes successfully
v::trueVal()->assert('yes');
// Validation passes successfully
v::trueVal()->assert('0.5');
// → "0.5" must evaluate to `true`
v::trueVal()->assert('2');
// → "2" must evaluate to `true`
```
