Add more tracing for SKSL compilation

Bug: b/179848728
Bug: b/146635333

We're seeing some slow shader_compiles on Android, so add some more
tracing to help determine where that time is being spent.

Use ATRACE_ANDROID_FRAMEWORK_ALWAYS instead of ATRACE_ANDROID_FRAMEWORK
for driver_compile_program and driver_link_program so that tracing for
the work done in the GPU driver will be turned on even if the developer
does not manually turn on skia tracing with

  adb shell setprop debug.hwui.skia_atrace_enabled true

This matches the "shader_compile" tag added in b/146635333 and allows
non-Skia developers to easily capture traces with more info.
