[0/2] Restructure va_high_addr_switch

Message

The va_high_addr_switch memory selftest tests out some corner cases
related to allocation and page/hugepage faulting around the switch
boundary. Currently, the page size and hugepage size have been statically
defined. Post FEAT_LPA2, the Aarch64 Linux kernel adds support for 4k and
16k translation granules on higher addresses; we restructure the test to
support the same. In addition, we avoid invocation of the binary twice,
in the shell script, to reduce test noise.
