refactor(Exception): improved the exception hierarchy and definitions.

[ishamisu]

Background
This update is part of the process to refactor the parser, moving from tsn-config-parser to a separation between common and domain-specific components. Exception has been identified as one of the necessary changes to finalize this separation.

Enhanced Exception Definition & Structure
Exception

|_ TCHConfigError (base for all TCH errors)
    |_ CommonConfigError (base for shared/common configuration concerns)
        |_ ConfigParseError (configuration file parsing failures)
        |_ ValidationError (configuration validation failures)
    |_ TSNConfigError (base for TSN domain errors)
        |_ TCCommandError (traffic control command execution failures)
        |_ InterfaceError (network interface operation failures)
    |_ TCCConfigError (base for TCC domain errors)
    |_ ServiceError (service management errors)

Changes

• Enhanced exception structure with both shared and domain specific errors.
• Modified the config parser service to utilize a common parsing error.
• Updated TCC and TSN to match the new exception definition.

Verification Result: ALL PASSED
