JDK-8269202: Support %p in jfr dump file name

[Hamlin-Li]

Currently, jfr supports 2 ways to name dump file.

1. dump without a file name, it will generate a name automatically with pid.
2. specify a file name explicitly, but without support for pid(%p)
   It will be helpful to support %p in file name.
