feat: manual compaction parallelism (#7086)

* feat/manual-compaction-parallelism:
 ### Add Parallelism Support to Compaction Requests

 - **`Cargo.lock` & `Cargo.toml`**: Updated `greptime-proto` dependency to a new revision.
 - **`flush_compact_table.rs`**: Enhanced `parse_compact_params` to support a new `parallelism` parameter, allowing users to
 specify the level of parallelism for table compaction.
 - **`handle_compaction.rs`**: Integrated `parallelism` into the compaction scheduling process, defaulting to 1 if not
 specified.
 - **`request.rs` & `region_request.rs`**: Modified `CompactRequest` to include `parallelism`, with logic to handle unspecifie
 values.
 - **`requests.rs`**: Updated `CompactTableRequest` structure to include an optional `parallelism` field.

 ### Commit Message

 Enhance Compaction Request Handling

 - **`flush_compact_table.rs`**:
   - Renamed `parse_compact_params` to `parse_compact_request`.
   - Introduced `DEFAULT_COMPACTION_PARALLELISM` constant.
   - Updated parsing logic to handle keyword arguments for `strict_window` and `regular` compaction types, including `parallelism` and `window`.
   - Modified tests to reflect changes in parsing logic and default parallelism handling.

 - **`request.rs`**:
   - Updated `parallelism` handling in `RegionRequestBody::Compact` to use the new default value.

 - **`requests.rs`**:
   - Changed `CompactTableRequest` to use a non-optional `parallelism` field with a default value of 1.

 ### Update `flush_compact_table.rs` Parameter Validation

 - Modified parameter validation in `flush_compact_table.rs` to restrict the maximum number of parameters from 4 to 3 in the `parse_compact_request` function.
