Update core-api

[kalkins]

The commit used for the core-api submodule is over a year old, and there have been many updates in the meantime.

For example, arduino/ArduinoCore-API#118 is only four commits after the one that is currently used, and it fixes a bug that made pgm_read_ptr unusable, breaking several libraries. This came up in sparkfun/Arduino_Apollo3#417.

I know that we can't just jump to the newest commit, there are breaking changes to consider, but can we at least try to get to version 1.1.0?

Forgot to close this issue.

This was fixed with commit c7a1dcad2a6e2d37253b0a12089550b470bdb0f5
