perf: Fix mmap_page capabilities and docs
Complete the syscall-less self-profiling feature and address
all complaints, namely:
- capabilities, so we can detect what is actually available at runtime
Add a capabilities field to perf_event_mmap_page to indicate
what is actually available for use.
- on x86: RDPMC weirdness due to being 40/48 bits and not sign-extending
properly.
- ABI documentation as to how all this stuff works.
Also improve the documentation for the new features.
