Remove linear filtering requirement on depth textures

Linear filtering depth is an odd operation that doesn't yield particularly useful information. In the primary instance where it'd be used, the GLES3.1 spec (8.17) specifically denies its use, and enforcing the capability can lead to issues with hardware designed without support in mind. We think the check isn't necessary as a result.
