bugfix: fix the problem that 'store mode' parameter does not take effect

[objcoding]

Ⅰ. Describe what this PR did

After the original store mode is split into session store mode and lock store mode, after old users upgrade to the new version, the store mode in the upgraded system will become invalid.
Solution:

1. Remove the default values of session store mode and lock store mode;
2. The store mode is reserved as a global setting.

This will make seata better compatible with the old version and more user-friendly upgrades.
