scudo/standalone: prepare for enabling format string checking
Move __attribute__((format)) to the function declarations in the header file.
It's almost pointless in the source file.
But disable the warning with -Wno-format for now
since there is a number of existing warnings.
Depends on D107984.

[scudo] Rework Vector/String
Some platforms (eg: Trusty) are extremelly memory constrained, which
doesn't necessarily work well with some of Scudo's current assumptions.
`Vector` by default (and as such `String` and `ScopedString`) maps a
page, which is a bit of a waste. This CL changes `Vector` to use a
buffer local to the class first, then potentially map more memory if
needed (`ScopedString` currently are all stack based so it would be
stack data). We also want to allow a platform to prevent any dynamic
resizing, so I added a `CanGrow` templated parameter that for now is
always `true` but would be set to `false` on Trusty.

[scudo] Rework dieOnMapUnmapError
Said function had a few shortfalls:
- didn't set an abort message on Android
- was logged on several lines
- didn't provide extra information like the size requested if OOM'ing
This improves the function to address those points.

[scudo][standalone] Fix tests under ASan/UBSan
Fix a potential UB in `appendSignedDecimal` (with -INT64_MIN) by making
it a special case.
Fix the terrible test cases for `isOwned`: I was pretty sloppy on those
and used some stack & static variables, but since `isOwned` accesses
memory prior to the pointer to check for the validity of the Scudo
header, it ended up being detected as some global and stack buffer out
of bounds accesses. So not I am using buffers with enough room so that
the test will not access memory prior to the variables.
With those fixes, the tests pass on the ASan+UBSan Fuchsia build.
Thanks to Roland for pointing those out!

[scudo][standalone] Get statistics in a char buffer
Summary:
Following up on D68471, this CL introduces some `getStats` APIs to
gather statistics in char buffers (`ScopedString` really) instead of
printing them out right away. Ultimately `printStats` will just
output the buffer, but that allows us to potentially do some work
on the intermediate buffer, and can be used for a `mallocz` type
of functionality. This allows us to pretty much get rid of all the
`Printf` calls around, but I am keeping the function in for
debugging purposes.
This changes the existing tests to use the new APIs when required.
I will add new tests as suggested in D68471 in another CL.
