Update Boost to 1.81

[AreaZR]

I will be the first to say it; I did in fact contribute to this release of Boost. However, it fixes a platitude of issues as this is a bugfix release.

Therefore, I think updating to 1.81 is worth it.

This assertion failed, but I failed to reproduce the error on Godbolt...

STL/tests/std/tests/LWG3234_math_special_overloads/test.cpp

Line 200 in 8ddf4da

assert(comp_ellint_2(0) == acos(-1.0) / 2);

Perhaps we can (temporarily) change this line as indicated (2 might be replaced with some suitable relative error)

assert(expect_epsilons(comp_ellint_2(0), acos(-1.0) / 2, 2));

You also need to update this commit hash to f395de082eca6ee993a15f2bdb90277eda518295:

STL/docs/cgmanifest.json

Lines 8 to 9 in 8ddf4da

	"repositoryUrl": "https://github.com/boostorg/math",
	"commitHash": "db2a7cbb44a84c4c9cba62232c07f18b22bd965d"

Done!

Perhaps we can (temporarily) change this line

@frederick-vs-ja Do we need to create an issue about this (here or maybe in boost-math repo)?

I think I've reproduced the error, so I reported the issue in boost-math repo.

FYI, I've verified that the commit hash corresponds to the boost-1.81.0 tag in the boost-math repo (https://github.com/boostorg/math/tags).

Error LNK2019: unresolved external symbol "void __cdecl std::swap<double,0>(double &,double &)" (??$swap@N$0A@@std@@YAXAEAN0@Z) referenced in function "bool __cdecl isclose<double>(double,double,int)" (??$isclose@N@@YA_NNNH@Z)

Adding #include <utility> fixed the test.

I'm mirroring this to the MSVC-internal repo - please notify me if any further changes are pushed.
