[Meson] update meson dependencies

[UnixY2K]

this PR only affects meson, however a later change could be made for CMake
updates the following dependencies:

• GTests to 1.14.0
• sqlite to 3.42.0
• C++11 is set and is on windows (this was Windows improved support (meson) #354 but now checks if is C++11 and shows a warning instead of setting it to C++14 so it does not revert when using a newer version)
• C++11 is set and uses GTest 1.14.0 or greater, for more information check Google's Foundational C++ Support Policy

getting an error on TravisCI
for the error in Windows latest clang seems to be due to a compiler version

[UnixY2K]

for windows-latest (clang) is caused due to a older version of clang, we could ignore it as it will be fixed in actions/runner-images#8125

Hello,
Yes, I noticed errors with Clang. It was possible to retry and get rid of it in the last few days, but not anymore (probably updating their images progressively)
And don't worry about Travis CI; it was blocked for months, saying I overused it and I was going to get rid of it... But I finally unlocked my account, and I now need to fix the outdated workflow

Hello @ninjaoflight, I fixed Travis CI with #450 🎉

And it's merged, thank you!
