Found while fuzzing. Previously 1.1897314953572317650857593266280070162E4932
was parsed as +inf, which caused issues for round-trip serialization of
floats. Only f128 had issues, but have added other tests for all
floating point large normals.
The max_exponent for f128 was wrong, it is subtly different in the
decimal code-path as it is based on where the decimal digit should go.
This needs to be 2 greater than the max exponent (e.g. 308 or 4932) to
work correctly (greater by 1, then we use a >= comparision).
In addition, I've removed the redundant `optimize` constant which was only
use for testing the slow path locally.
std.heap.c_allocator was already doing this, however,
std.heap.raw_c_allocator, which asserts no allocations more than 16
bytes aligned, was not.
The zig compiler uses std.heap.raw_c_allocator, so it is affected by
this.
Like in issue #18089, this tar contains, same file name in two case
sensitive name version. Unpack should fail on case insensitive file
systems and succeed on case sensitive.

Windows paths now use WTF-16 <-> WTF-8 conversion everywhere, which is lossless. Previously, conversion of ill-formed UTF-16 paths would either fail or invoke illegal behavior.
WASI paths must be valid UTF-8, and the relevant function calls have been updated to handle the possibility of failure due to paths not being encoded/encodable as valid UTF-8.
Closes#18694Closes#1774Closes#2565
Ill-formed UTF-8 byte sequences are replaced by the replacement character (U+FFFD) according to "U+FFFD Substitution of Maximal Subparts" from Chapter 3 of the Unicode standard, and as specified by https://encoding.spec.whatwg.org/#utf-8-decoder
