Fix string indexing bug with Phi-4 mm tokenization (microsoft#1751)

### Description

This PR brings in two new out-of-bounds checks when running each step
while matching the first Phi-4 multimodal pattern during tokenization.

### Motivation and Context

These checks were added to ORT extensions in [this
PR](microsoft/onnxruntime-extensions#997).
Without these checks, the following error can happen in some
environments.

```
/opt/rh/gcc-toolset-12/root/usr/include/c++/12/string_view:239: constexpr const std::basic_string_view<_CharT, _Traits>::value_type& std::basic_string_view<_CharT, _Traits>::operator[](size_type) const [with _CharT = char32_t; _Traits = std::char_traits<char32_t>; const_reference = const char32_t&; size_type = long unsigned int]: Assertion '__pos < this->_M_len' failed.
```
