Alexandre Gomes Gaigalas c523b856e7 Introduce Trimmed validator
This commit introduces the `Trimmed` validator that ensures a string
cannot start or end with a list of specific values.

The default values used are a selected list of Unicode invisible
characters.

To support this change, the StartsWith and EndsWith validators were
modified so they can also support multiple values to check for.

While StartsWith and EndsWith are more generic, and also perform
start-of-array and end-of-array kinds of checks, Trimmed is more
focused on string inputs, which tailors to a more specific use
case.

# EndsWith
- `EndsWith(mixed $endValue)`
- `EndsWith(mixed $endValue, mixed ...$endValues)`
This validator is similar to `Contains()`, but validates
only if one of the values is at the end of the input. Only
string inputs and string end values are checked; nonstring
values are considered invalid but will not produce PHP errors
thanks to internal type guards.
For strings (non-string inputs are always rejected):
```php
v::endsWith('ipsum')->assert('lorem ipsum');
// Validation passes successfully
v::endsWith(', PhD', ', doctor')->assert('Jane Doe, PhD');
// Validation passes successfully
```
For arrays:
```php
v::endsWith('ipsum')->assert(['lorem', 'ipsum']);
// Validation passes successfully
v::endsWith('.', ';')->assert(['this', 'is', 'a', 'tokenized', 'phrase', '.']);
// Validation passes successfully
v::endsWith('.', ';')->assert(['this', 'is', 'a', 'tokenized', 'phrase']);
// → `["this", "is", "a", "tokenized", "phrase"]` must end with "." or ";"
```
Message template for this validator includes `{{endValue}}` and `{{endValues}}`.
