a11y: Merge accessibility module into vcl

In an upcoming Gerrit change [1] that namespace was
now causing ambiguity in source files using

using namespace css::uno;

because a simple `accessibility` namespace specifier
could now be for either the `accessibility` namespace
removed with this commit or `css::uno::accessibility`.

Sample from Windows CI failure [2]:

C:/cygwin64/home/tdf/jenkins/workspace/gerrit_windows/vcl/source/accessibility/vclxaccessiblecomponent.cxx(112): error C2872: 'accessibility': ambiguous symbol
C:\cygwin64\home\tdf\jenkins\workspace\gerrit_windows\vcl\inc\accessibility/accessibletablistbox.hxx(29): note: could be 'accessibility'
C:\cygwin64\home\tdf\jenkins\workspace\gerrit_windows\include\vcl/accessibility/vclxaccessiblecomponent.hxx(31): note: or       'com::sun::star::accessibility'
C:/cygwin64/home/tdf/jenkins/workspace/gerrit_windows/vcl/source/accessibility/vclxaccessiblecomponent.cxx(112): error C2039: 'XAccessibleContext': is not a member of 'accessibility'

Drop the namespace to avoid having to always specify
the whole namespace (`css::uno::accessibility` vs `::accessibility`).

(`git show --ignore-space-change` shows the "actual
changes" more clearly as some code was using an
extra indentation level due to the namespace
that has been removed along with the namespace.)
