POWER11 will GA next year. It needs to be recognized now in order to align runtime release with it. Before OpenJ9 can switch to using OMR's CPU recognition code completely, it is necessary to recognize future POWER processors correctly but as closely as possible for performance purposes before the relevant macro is officially available from AIX system header files. A catch-all macro for future processors is defined as well. Signed-off-by: Julian <[email protected]>

Cherry pick zl-wang@cfce6b2 and remove the unused __power_11 macro.
This will recognize POWER11 in the 0.49 release in advance of a more complicated solution (#20668) that uses OMR instead.
