Windows Sandbox: update capability for SandboxType::kMediaFoundationCdm

This CL is to replace lpacAppServices with lpacInstrumentation for
SandboxType::kMediaFoundationCdm.

https://chromium-review.googlesource.com/c/chromium/src/+/2401506 has
a mistake of using lpacAppServices. Windows Media Foundation needs
lpacInstrumentation capability to access Windows Event Tracings and
Telemetries.
