When reworking btf__get_from_id() in commit a19f93cfaf the error
handling when calling bpf_btf_get_fd_by_id() changed. Before the rework
if bpf_btf_get_fd_by_id() failed the error would not be propagated to
callers of btf__get_from_id(), after the rework it is. This lead to a
change in behavior in print_key_value() that now prints an error when
trying to lookup keys in maps with no btf available.
Fix this by following the way used in dumping maps to allow to look up
keys in no-btf maps, by which it decides whether and where to get the
btf info according to the btf value type.

Instead of hard coding a small amount of tests, generate a wider
range of tests to try catch any corner cases that could show up.
These new tests test different MTE tag lengths and offsets, which
previously would have caused infinite loops in the kernel. This was
fixed by 295cf15623 ("arm64: Avoid premature usercopy failure"),
so these are regressions tests for that corner case.

These can be used to place an MTE tag at an address that is not at a
page size boundary.
The kernel prior to 295cf15623 ("arm64: Avoid premature usercopy failure"),
would infinite loop if an MTE tag was placed not at a PAGE_SIZE boundary.
This is because the kernel checked if the pages were readable by checking the
first byte of each page, but would then fault in the middle of the page due
to the MTE tag.

To support larger hash digests in the 'iint' cache, instead of defining
the 'digest' field as the maximum digest size, the 'digest' field was
defined as a flexible array variable. The "ima_digest_data" struct was
wrapped inside a local structure with the maximum digest size. But
before adding the record to the iint cache, memory for the exact digest
size was dynamically allocated.
The original reason for defining the 'digest' field as a flexible array
variable is still valid for the 'iint' cache use case. Instead of
wrapping the 'ima_digest_data' struct in a local structure define
'ima_max_digest_data' struct.

While in this particular case it would not be a (critical) issue,
the pattern itself is bad and error prone in case somebody blindly
copies to their code.
Don't cast parameter to unsigned long pointer in the bit operations.
Instead copy to a local variable on stack of a proper type and use.
Note, new compilers might warn on this line for potential outbound access.
