This pull request includes changes to rename functions related to KDA NFT name and URI length to more general names, reflecting a broader use case. The changes are applied across multiple files to ensure consistency. The most important changes include updates to function pointers, trait implementations, and import objects.

Function renaming:

• c-api/src/capi_vm_hook_pointers.rs: Renamed get_kda_nft_name_length_func_ptr and get_kda_nft_uri_length_func_ptr to get_kda_name_length_func_ptr and get_kda_uri_length_func_ptr respectively.
• c-api/src/capi_vm_hooks.rs: Updated function names in the VMHooks implementation from get_kda_nft_name_length and get_kda_nft_uri_length to get_kda_name_length and get_kda_uri_length.

Import object updates:

• vm-executor-wasmer/src/wasmer_imports.rs: Modified the import functions to reflect the new names get_kda_name_length and get_kda_uri_length. [1] [2]

Trait and implementation updates:

• vm-executor/src/vm_hooks.rs: Updated the VMHooks trait and its default implementation to use the new function names get_kda_name_length and get_kda_uri_length. [1] [2]
