Remove "Ada Settings" node from the manual

A while back, I sent a patch to unify the Ada varsize-limit setting
with the more generic max-value-size:

https://sourceware.org/pipermail/gdb-patches/2021-September/182004.html

However, it turns out I somehow neglected to send part of the patch.
Internally, I also removed the "Ada Settings" node from the manual, as
it only documents the obsolete setting.

This patch removes this text.

-Prevent @value{GDBN} from attempting to evaluate objects whose size
-is above the given limit (@var{size}) when those sizes are computed
-from run-time quantities.  This is typically the case when the object
-has a variable size, such as an array whose bounds are not known at
-compile time for example.  Setting @var{size} to @code{unlimited}
-removes the size limitation.  By default, the limit is about 65KB.

-The purpose of having such a limit is to prevent @value{GDBN} from
-trying to grab enormous chunks of virtual memory when asked to evaluate
-a quantity whose bounds have been corrupted or have not yet been fully
-initialized.  The limit applies to the results of some subexpressions
-as well as to complete expressions.  For example, an expression denoting
-a simple integer component, such as @code{x.y.z}, may fail if the size of
-@code{x.y} is variable and exceeds @code{size}.  On the other hand,
-@value{GDBN} is sometimes clever; the expression @code{A(i)}, where
-@code{A} is an array variable with non-constant size, will generally
-succeed regardless of the bounds on @code{A}, as long as the component
-size is less than @var{size}.
