Important changes

[API] Add InstrumentationScope attributes in MeterProvider::GetMeter()

#2224

MeterProvider::GetMeter() now accepts InstrumentationScope attributes.
Because this is an ABI breaking change, the fix is only available

with the CMake option WITH_ABI_VERSION_2=ON.
When building with CMake option WITH_ABI_VERSION_1=ON (by default)

the ABI is unchanged, and the fix is not available.



Breaking changes


[BUILD] Need fine-grained HAVE_CPP_STDLIB

#2304

In CMAKE, the boolean option WITH_STL as changed to an option

that accepts the values OFF, ON, CXX11, CXX14, CXX17,

CXX20 and CXX23.
Applications makefiles that did not set WITH_STL need to use

WITH_STL=OFF instead (this is the default).
Applications makefiles that did set WITH_STL need to use

WITH_STL=ON instead, or may choose to pick a specific value.
In the API header files, the preprocessor symbol HAVE_CPP_STDLIB

is no longer used.
Applications that did set HAVE_CPP_STDLIB before, need to set

OPENTELEMETRY_STL_VERSION=<version> instead, to build with a

specific STL version (2011, 2014, 2017, 2020, 2023).
The opentelemetry-cpp makefile no longer sets

CMAKE_CXX_STANDARD by itself.

Instead, the CMAKE_CXX_STANDARD and/or compiler options -stdc++ used

by the caller are honored.
Applications that set neither CMAKE_CXX_STANDARD nor -stdc++

options may need to provide a C++ standard in their makefiles.



[REMOVAL] Drop C++11 support

#2342

Building with C++11 is no longer supported.
