* llama : add inference support and model types for T5 and FLAN-T5 model families
* llama : add new API functions to support encoder-decoder models: llama_encode(), llama_model_has_encoder(), llama_model_decoder_start_token()
* common, llama-cli, llama-batched : add support for encoder-decoder models
* convert-hf : handle shared token embeddings tensors in T5Model
* convert-hf : add support for SentencePiece BPE tokenizer in T5Model (for Pile-T5 models)
* convert-hf : add MT5ForConditionalGeneration and UMT5ForConditionalGeneration to architectures supported by T5Model
* convert : add t5 tokenizer tests, use "slow" HF tokenizer for t5

This commit adds the compile definition `_CRT_SECURE_NO_WARNINGS`
to the root cmake subproject.
The motivation for this is that currently the following warnings are
displayed when compiling the tests and common cmake subprojects:
```console
test-llama-grammar.cpp
C:\llama.cpp\src\.\llama.cpp(1406,77): warning C4996: 'strerror':
This function or variable may be unsafe. Consider using strerror_s
instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See
online help for details.
[C:\llama.cpp\build\tests\test-llama-grammar.vcxproj]
...
```
This compile definition is currently set for the `src` subproject
and this change moves into the root cmake project so that it is applied
to all cmake subprojects.
