Log Message:
-----------
SecurityPkg/RngDxe: Correctly update mAvailableAlgoArrayCount
mAvailableAlgoArrayCount holds the count of available RNG algorithms.
In a following patch, its value will be used to prevent the
EFI_RNG_PROTOCOL to be installed if no RNG algorithm is available.
Correctly set/reset the value for all implementations.

Log Message:
-----------
SecurityPkg/RngDxe: Conditionally install EFI_RNG_PROTOCOL
On Arm platforms, the number of available RNG algorithms is
dynamically detected and can be 0 in the absence of FEAT_RNG
and firmware TRNG.
In this case, the EFI_RNG_PROTOCOL should not be installed to
prevent from installing an empty protocol.
