[HALX86/APIC] Change IRQL for x86 profile interrupt to HIGH_LEVEL

Browse source 
While PROFILE_LEVEL is defined as 27 on x86, this does not match the vector for the profiling interrupt, which is 0xFD (see https://community.osr.com/t/odd-ioapic-output/45216), implying IRQL 31.
Fixes boot with x86 APIC hal (CORE-20093)
