a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT
...
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.
Test added to confirm fix.

fuzz_with_unicorn: Move std::vector outside loop in small random block test case
...
Avoids constructing and destructing the vector repeatedly, we can just
alter the contents of the vector on each iteration instead. Also move
out the std::array instances as well, like with the floating-point test
case and the single random instruction test case.
We can also use the regular form of std::generate and avoid hardcoding
size values twice.
