[Mac] Bump the LSMinimumSystemVersion to 10.10.0

Chromium dropped support for macOS 10.9 but did not bump the
LSMinimumSystemVersion. The Info.plist key was tied to the
MACOSX_DEPLOYMENT_TARGET, but because there is still outstanding work to
update that, the value does not reflect the real requirement.

This introduces a new GN variable mac_min_system_version that is used
for the LSMinimumSystemVersion, so that it can be controlled
independently of the GN variable mac_deployment_target.

Bug: 806071, 841631, 848769
Test: Chromium.app/Contents/Info.plist has a LSMinimumSystemVersion of 10.10.0
