  [profile] Add a clang option -fprofile-continuous that enables continuous instrumentation profiling mode (#124353)

In Continuous instrumentation profiling mode, profile or coverage data
collected via compiler instrumentation is continuously synced to the
profile file. This feature has existed for a while, and is documented
here:

https://clang.llvm.org/docs/SourceBasedCodeCoverage.html#running-the-instrumented-program
This PR creates a user facing option to enable the feature.
