UCP: Support generating profiling graph without go and pprof

[rleungx]

Description

Currently, we can get profiling results through API /profile. TiKV will return the file with the extension .svg directly, but go based program such as TiDB and PD will need to use go tool pprof -svg to convert the results to .svg file.

In this case, we need to install go which is too noisy. A possible way to avoid installing go is moving part of code from github.com/google/pprof. Another way is to use driver.PProf, but need to find a way to solve the concurrency problem of output.
