Suppress build: masm logo and clang warning argument unused during compilation

[Challanger524]

PR for: #286 and #287

Concern

These changes are applied to implementation fcontext (that is being set for me):

[build] -- Boost.Context: architecture x86_64, binary format pe, ABI ms, assembler gas, suffix .asm, implementation fcontext

Maybe old code + new mine should affect other implementations (ucontext, winfib) too, maybe not - I don't know.

Further

There still MASM output that informs/repeats the build file, looks like modern VS 2022 17.7 Preview 1 is able to consume /quiet option for ml and ml64. But it is too modern :(

/quiet	Suppresses 'Assembling' message. Available in Visual Studio 17.6 and later.

CMake - GREATER_EQUAL

Added in version 3.7: Added the LESS_EQUAL and GREATER_EQUAL options.
And context is 3.5: if(NOT(MSVC_VERSION LESS 1936)) will it be

Concern

It is better to check if we can pass /quiet on any 17.6 patch version, or better to set 1937 to be 100% sure that it works.

Just pulled updated boost/context with my PR fixes. It is so awesome to see those same fixes working without any local changes! Thank you for reviewing (hope it was reviewed) and somehow tested, since I don't see any CMake related CI/CD Actions.
