Masayuki Nakano 2e477396b8 Bug 1840568 - Make TSFTextStore allow to flush layout at query content only when it's not called recursively r=m_kato 
By default, query content allows to flushing layout.  In most cases, this should
not cause recursive call of the caching content/selection methods.  However,
according to a crash report, this may occur with no chance to avoid the loop
from `TSFTextStore` point of view.  Fortunately, the recursive call may happen
only when an element in chrome in the main process has focus.  Therefore, I
think that we can keep current `MOZ_DIAGNOSTIC_ASSERT`s in the methods, but the
nested call should not allow to flush pending layout to avoid an infinite loop
in the release channel.
