This prevents accidentally writing fmt::format when fmt::print was
intended. Other than running tests, there's not a good use case for
discarding the formatted output.
* all GTest/GMock files moved to `test/gtest` directory
* `CMakeLists.txt` created in `test/gtest` from `CMakeLists.txt` in `test`
* GTest/GMock target in CMake renamed to `gtest` (was `gmock`)
* CMake `gtest` target updated to export includes as "gtest/gtest.h" or "gmock/gmock.h" only
* includes in tests updated: "gtest.h" -> "gtest/gtest.h", "gmock.h" -> "gmock/gmock.h"
* removed duplications of `target_include_directories` for GTest/GMock directories (CMake manages them)
Passing a function pointer to fmt::ptr results in:

with GCC and Clang. Let's add an overload to support that usage.
Unfortunately, MSVC would
consider the overload to be ambiguous for unknown reasons:
D:\a\fmt\fmt\test\format-test.cc(1485,1): error C2668: 'fmt::v7::ptr': ambiguous call to overloaded function [D:\a\fmt\build\test\format-test.vcxproj]

]

]
D:\a\fmt\fmt\test\format-test.cc(1486,1): message : while trying to match the argument list '(overloaded-function)' [D:\a\fmt\build\test\format-test.vcxproj]
but luckily this means that the overload is unnecessary in that case
anyway, so we can just make it conditional.
* add test for byte formatting with `FMT_COMPILE`
* fix byte formatting with `FMT_COMPILE`, use `__cpp_lib_byte` macro
* use is not custom mapped type check
* workaround MSVC bug
