fix: #2883 pickle data was truncated error in database session using MySql

Merge https://github.com/google/adk-python/pull/2884

closes: #2883
# Fix
When put leage data into event and load it. the _pickle.UnpicklingError was occurred.
The root caurse is `DynamicPickleType` mapping `BLOB` as default in case of MySql, not `LONGBLOB`. And learge data will be able to cut off tail of data. And raise pickle error.

# What todo
Defined `LONFBLOB` as default explicitly.

# Question
Where should we code the test code like this case? I cannot found the test code the DB and table was created expectedly.
