Respect server capabilities on queries (#33538)

Closes https://github.com/zed-industries/zed/issues/33522

Turns out a bunch of Zed requests were not checking their capabilities
correctly, due to odd copy-paste and due to default that assumed that
the capabilities are met.

Adjust the code, which includes the document colors, add the test on the
colors case.

Release Notes:

- Fixed excessive document colors requests for unrelated files
