HV: treewide: fix violations of coding guideline C-TY-27 & C-TY-28

Browse Source 
The coding guideline rules C-TY-27 and C-TY-28, combined, requires that
assignment and arithmetic operations shall be applied only on operands of the
same kind. This patch either adds explicit type casts or adjust types of
variables to align the types of operands.

The only semantic change introduced by this patch is the promotion of the
second argument of set_vmcs_bit() and clear_vmcs_bit() to
uint64_t (formerly uint32_t). This avoids clear_vmcs_bit() to accidentally
clears the upper 32 bits of the requested VMCS field.

Other than that, this patch has no semantic change. Specifically this patch
is not meant to fix buggy narrowing operations, only to make these
operations explicit.
