  [TSAN][RISCV] Fix kHiAppMemEnd boundary for riscv64 (#191170)

This resolves TSan execution failures on riscv64 platforms when Address
Space Layout Randomization (ASLR) is disabled. There was an off-by-one
error in `tsan_platform.h` that caused the sanitizer to fail when memory
is mapped at the edge under non-ASLR environments. We fix this by
extending `kHiAppMemEnd` to cover the full allowed memory range:

`MappingRiscv64_39`: `0x3fffffffffull` -> `0x4000000000ull`
     `MappingRiscv64_48`: `0x7fffffffffffull` -> `0x800000000000ull`

We also add riscv64 test support to `pie_no_aslr.cpp`
