llama : suppress conversion from 'size_t' to 'int' (#9046)

* llama : suppress conversion from 'size_t' to 'int'

This commit updates llm_tokenizer_spm.tokenize to suppress/remove the
following warnings that are generated on Windows when using MSVC:

```console
src\llama-vocab.cpp(211,1): warning C4267: 'argument':
    conversion from 'size_t' to 'int', possible loss of data
src\llama-vocab.cpp(517,1): warning C4267: 'argument':
    conversion from 'size_t' to 'int', possible loss of data
```

This is done by adding a cast for the size_t returned from
symbols.size(). I believe this is safe as it seems unlikely that
symbols, which stores an entry for each UTF8 character, would become
larger than INT_MAX.

The motivation for this change is to reduce the number of warnings that
are currently generated when building on Windows.

* squash! llama : suppress conversion from 'size_t' to 'int'

Move cast into for loop.
