refactor(cli): move LZ4 block-size policy leaf to Rust

Browse Source 
Export FIO_LZ4_GetBlockSize_FromBlockId directly from Rust under the existing
caller symbol and remove the redundant C forwarding wrapper. Preserve the
block-ID formula and cover its boundary values in the focused Rust test.

Test Plan:
- worker capped nightly rustfmt check
- worker git diff --check
- full serial capped native and upstream suites to run at the next parent gate
