powercap: intel_rapl: Move MSR primitives to MSR driver

MSR-specific RAPL primitives differ from those used by TPMI and MMIO
interfaces. Keeping them in the common driver requires
interface-specific handling logic and makes the common layer
unnecessarily complex.

Move the MSR primitive definitions and associated bitmasks into the
MSR interface driver. This change includes:

 1. Move MSR-specific bitmask definitions to RAPL MSR driver.
 2. Add MSR-local struct rapl_primitive_info instance and assign it to
    priv->rpi during MSR probe.
 3. Remove the primitive assignment logic from rapl_config() in the
    common driver.

No functional changes are intended.
