Brandon DeRosier 739db9f5b5 [Impeller] Avoid invalid GL depth calls on macOS desktop. (flutter/engine#46758) ...

The macOS desktop driver doesn't support ES profiles, and
`glClearDepthf` + `glDepthRangef` are throwing `GL_INVALID_OPERATION`
and doing nothing. Noticed this while updating impeller-cmake past
@matanlurey's recent changes to make `GL_INVALID_OPERATION` fatal.
Impeller-cmake-example uses a depth buffer, whereas Impeller's 2D
renderer currently does not.

Added a follow-up bug to make these calls work on macOS desktop:
https://github.com/flutter/flutter/issues/136322.
Both Impeller Scene and the impeller-cmake-example currently just rely
on the default state for clearing depth.
