  [BOLT][AArch64] Fixes assertion errors occurred when perf2bolt was executed (#83394)

BOLT only checks for the most common indirect branch pattern during the
branch analyzation.
Extended the logic with two other indirect patterns which slightly
differ from the expected one.
Those patterns may be hit when statically linking libc (pattern 2
requires 'lld' linker).

As a workaround mark them as UNKNOWN branch for now. 

Fixes: #83114
