Support verifying the boot signature against the given pubkey.

verify_boot_signature currently verifies the signature in the boot image
(against the certificate embedded in the image).

This CL supports additionally verifying the signature against the given
OEM pubkey (a fixed, tamper-protected key available to the bootloader).

Usage: verify_boot_signature <path-to-boot-image>
       verify_boot_signature <path-to-boot-image> <pubkey>

- Locally built boot image is signed with the default key.
$ openssl x509 -pubkey -noout -in build/target/product/security/verity.x509.pem > pubkey.pem
$ verify_boot_signature $OUT/boot.img pubkey.pem; echo $?
Signature is VALID
0

- Signed boot image should be verified with the OEM pubkey.
$ verify_boot_signature boot.img bullhead_pub.pem; echo $?
Signature is VALID
0

- Locally built boot image can be verified with its embedded certificate
  but not with the OEM pubkey. This will lead to the YELLOW boot state.
$ verify_boot_signature $OUT/boot.img; echo $?

simpleperf: handle monitored processes correctly when a cpu is up.

For stat/record cmd, the way to handle -p option is to change the
process list into a thread list before profiling. However, it doesn't
work well if we want to open new event files when a cpu is up. The
situation in problem is as below:

1. Monitor for process A, which currently has thread a.
2. Then we open event files for thread a.
3. Process A creates thread b. If profiling child threads/processes
is enabled, the kernel will monitor thread b automatically.
4. A new cpu is up, and we need to open new event files on that
cpu. But we will only open event file for thread a, although the
user command is to monitor the whole process.

To fix this, remember which processes are monitored in
EventSelectionSet, and search threads in the monitored processes
each time to open new event files.
