Why this change is necessary and useful

ycm-core/ycmd@master contains a recent fix that updates its dependency on gopls to the latest version, 0.16.1 (commit). Updating the submodule here ensures that users will get this fix and be using the latest version of gopls.

As a contributor, I am opening this PR because the prior version of gopls that ycmd used, 0.15.3, contained a bug that is interrupting my workflow. Fortunately ycmd has already upgraded, so updating the submodule in YouCompleteMe is the only change that would be needed to fix it.

Thank you for your consideration!

Thanks!

I was hoping to get ycm-core/ycmd#1752 merged before we update the ycmd submodude, but oh well.
That pull request is stuck on getting C# to cooperate on windows.

Meanwhile, I knew we'd have users hitting this gopls thing.

Changelog since last update:

• Abseil update, which should fix build errors on FreeBSD.
• Automatically discovering the build tool path/version on Windows should work again.
• Gopls update.
• Preparing for moving C# to LSP

I've allowed CI on this pull request.

@msteffen Last night I've merged some things for C# and Java. Can you update the ycmd submodule again?
