feat(derive): Add better string parsing support

[GeekMasher]

This pull request includes several enhancements and new features to the geekorm-derive library. The most important changes involve adding new attribute keys, improving parsing logic, and extending support for additional data types and functionalities.

Enhancements to attribute keys and parsing logic:

• geekorm-derive/src/attr.rs: Added new attribute keys (Key, Aliases, OnValidate, Disable) and updated the GeekAttribute struct to include a Vec<String> type. Improved parsing logic to handle these new keys and their respective values. [1] [2] [3] [4] [5] [6] [7]

Enhancements to ColumnDerive:

• geekorm-derive/src/derive/column.rs: Added handling for the OnValidate attribute key to set the save and update properties accordingly. Updated logic to skip certain attribute keys (Key, Disable, Aliases). [1] [2]

Support for custom key attributes in enums:

• geekorm-derive/src/lib.rs: Demonstrated usage of the key attribute in documentation comments and updated the data_derive function to include geekorm attributes. [1] [2]
• geekorm-derive/src/parsers.rs: Added generate_strings function to support custom key attributes for enum variants, and integrated this function into the enum_parser. [1] [2]

Miscellaneous improvements:

• geekorm-derive/src/parsers/tablebuilder.rs: Removed unnecessary logging code in the generate_backend function.
• geekorm-derive/src/parsers/values.rs: Added support for custom key attributes in the generate_from_value function and implemented generate_strings for ToString and Display traits. Improved serde serialization and deserialization implementations. [1] [2] [3] [4] [5] [6] [7] [8]
