[Silabs] Add more gn arg to configure NVM3. (#35717)
Add two new gn arg(sl_nvm3_nvm_size and sl_nvm3_cache_size) to configure NVM3.
Developers can analyze their storage needs to adjust these two parameters, which can effectively improve storage efficiency.
Especially after https://github.com/project-chip/connectedhomeip/pull/35480, developers would like to adjust these configuration.
