[JSC] Add useCompilerSignpost option to emit signpost with compiled function
information
https://bugs.webkit.org/show_bug.cgi?id=268067
rdar://121584775
Reviewed by Ryosuke Niwa.
This patch adds a JSC option, useCompilerSignpost, which can emit signpost for
JSC JIT Compiler activities.
We record function name etc. as an interval signpost to investigate compiler
activities in the complicated workload.
We also adjust JITCompilationMode's string to make it more modern and readable.
