240f510fa7 Core ubsan fixes 
This fixes UBSAN errors reported by running our testsuite, importing the
TPS demo, and running the TPS demo. I have tried, wherever possible, to
fix issues related to reported issues but not directly reported by UBSAN
because thse code paths just happened to not have been exercised in
these cases.

These fixes apply only to errors reported, and caused by, core/

The following things have been changed:

* Make sure there are no implicit sign changing casts in core.
* Explicitly type enums that are part of a public API such that users of
  the API cannot pass in wrongly-sized values leading to potential stack
  corruption.
* Ensure that memcpy is never called with invalid or null pointers as
  this is undefined behavior, and when the engine is built with
  optimizations turned on leads to memory corruption and hard to debug
  crashes.
* Replace enum values only used as static values with constexpr static
  const values instead. This has no runtime overhead. This makes it so
  that the size of the enums is explicit.
* Make sure that nan and inf is handled consistently in String.
* Implement a _to_int template to ensure that all of the paths use the
  same algorhithm, and correct the negative integer case.
* Changed the way the json serializer precision work, and added tests to
  verify the new behavior. The behavior doesn't quite match master in
  particulary for negative doubles as the original code tried to cast -inf
  to an int. This then led to negative doubles losing all but one of
  their decimal points when serializing. Behavior in GDScript remains
  unchanged.

b3b24ded19 Add checks for valid base in String::num_int64, uint64(). 
- Ensure String::num_int64, uint64 returns an empty string for bases less than 2 or greater than 36.
- Added corresponding test cases to verify the behavior.
- Error messages are printed when invalid bases are encountered. These messages are suppressed in the test output.

use operator += (char32_t) 
This prevents an allocation of a new string for every character.

Additionally, use some static constants for padding and sign characters

Replace find with contains/has where applicable 
* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
