[Android] Remove about:flags entry for low-end device mode

[Android] Remove about:flags entry for low-end device mode

Release builds of Android use specialized code for loading shared libraries.
The code queries |isLowEndDevice()| before about:flags has propagated to the
process command-line, yielding inconsistent low-end device configurations
between processes.  This can potentially lead to a state where all tabs are
blank, forcing the user to re-install Chrome. Remove the about:flags entry
until the query can be either deferred or removed entirely.

yfriedman@: I'd like to disable this entirely until we get a proper solution, in
particular so we can cherry-pick to M33 before it hits beta.  I don't want users
getting burned by this setting (they can still use a command-line flag to
override the setting).
