Make sure we exit the loop when reading the file in chunks in
wxFile::ReadAll() and add a unit test for it to ensure that it's really
correct.
Closes#14725.

The test was intended to verify that round trip via wxFile::Write/Read()
worked even for the strings with embedded NULs but as the string wasn't
constructed correctly it didn't actually contain any NULs but was ended by the
first of them.
Fix this by using explicit length of the string as usual when dealing with
strings with embedded NULs. Also fix the conversion back to Unicode to use the
correct length.

These tests didn't work correctly in ANSI build because the conversion
parameter of wxFile::Write() isn't used there, the contents of an ANSI
wxString is always written to the file as is -- hence reading it back using
UTF-16 or UTF-32 conversion fails.
The test would need to be totally rewritten for ANSI build of wx and it
wouldn't test wxFile but rather conversion functions already tested elsewhere
so just disable it instead.
This fixes a crash (due to passing NULL pointer to memcmp()) which prevented
the test suite from running to completion in ANSI build.

wxFileOffset and ssize_t are not the same type under this platform so using
CPPUNIT_ASSERT_EQUAL() with the arguments of these types fails. Use ssize_t
instead of wxFileOffset to fix this.

This function was broken for conversions using more than one byte per
character (e.g. UTF-16 or UTF-32) and also even for UTF-8 for strings
containing NUL bytes as it used strlen() to determine the number of bytes to
write out instead of using the really needed number.
Fix this by using the wxCharBuffer::length() method which always returns the
correct value.
Also add a wxFile unit test verifying that it can correctly read back a string
written using any of UTF-8, UTF-16 or UTF-32.
