  [Sanitizer][RISCV][AArch64][Android] Adjust allocator tests

On 64-bit systems with small VMAs (e.g. 39-bit) we can't use
`SizeClassAllocator64` parameterized with size class maps containing a
large number of classes, as that will make the allocator region size too
small (< 2^32). Several tests were already disabled for Android because
of this.

This patch provides the correct allocator configuration for RISC-V
(riscv64), generalizes the gating condition for tests that can't be
enabled for small VMA systems, and tweaks the tests that can be made
compatible with those systems to enable them.
