Refresh external image cache on symbolization misses.
...
FindExternalImageRefresh already re-parsed /proc/<pid>/maps on miss,
but only one of three external decode paths used it. Switch the
DecodeCallstackPtrFastExternal and DecodeSymbolAddressExternal paths
over so symbol-name and file/line lookups stay fresh after the target
dlopens a library.
Rate-limit the re-parse to once per wall-clock second so samples
landing on permanently unresolvable regions (JIT, vDSO, stacks) do
not trigger a full parse each time.

Add static cast to uint64_t for std::min
...
On 32-bit arm, phdr.p_vaddr is 32-bit, which causes a compilation
error because std::min expects both arguments to be of the same
type. Adding the static cast handles this case explicitly.

Rename ImageCache::Contains to ContainsImage

The name was a bit misleading as it could be mistaken to mean "The cache contains the address" and not as "has an image with this start address". ie: that it could be mistaken to do GetImageForAddress( startAddress ) != nullptr.

Fix delay loading by not exporting variables
...
[`/DELAYLOAD`](https://learn.microsoft.com/en-us/cpp/build/reference/delayload-delay-load-import?view=msvc-170 ) only works with exported functions, not variables (as it patches thunks after the first load).
So instead of using exporting a pointer for `___tracy_RtlWalkFrameChain`, make it a function that will call said pointer. This only adds a `mov`+`jmp` instructions in optimized builds to the call, which is negligible compared to the actual cost of RtlWalkFrameChain. This also does not affect the reported callstack since it will use a `jmp` without touching the stack, so `___tracy_RtlWalkFrameChain` won't appear in the capture stacktrace.
