runtime: make the test addresses for pageAlloc smaller on 32-bit
This change makes the test addresses start at 1 GiB instead of 2 GiB to
support mips and mipsle, which only have 31-bit address spaces.
It also changes some tests to use smaller offsets for the chunk index to
avoid jumping too far ahead in the address space to support 31-bit
address spaces. The tests don't require such large jumps for what
they're testing anyway.
Updates #35112.
Fixes #35440.
