A64/fuzz_with_unicorn: Avoid repeated unnecessary library calls in RunTestInstance()
...
Repeatedly retrieving the vectors and registers from unicorn involves
copying the entire set of registers and vectors by value instead of
simply retrieving a reference to them. Instead, we can just do the work
once and print out the values.
While we're at it, also make our bracing consistent.

ir/value: Replace includes with forward declarations
...
enum classes are still considered complete types when forward declared
(as the compiler knows the exact size of the type from the declaration
alone). The only difference in this case being that the members of the
enum class aren't visible. Given we don't use the members within this
header in any way, we can simply forward declare them here and remove
the inclusions.

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.

Avoids constructing and destructing the vector repeatedly, we can just

case and the single random instruction test case.
We can also use the regular form of std::generate and avoid hardcoding
size values twice.
