Patrick Thier 6ff1129ca3 [sparkplug] Batch compilation 
Instead of compiling a function with baseline immediately when the
interrupt budget is hit, we compile functions in batches to save some
memory protection flips on code pages.

This CL introduces batch compilation behind --baseline-batch-compilation
(enabled on future) and adds a flag
--baseline-batch-compilation-threshold to control the size of batches.

Bug: v8:11790
