[libc++][NFC] Add additional tests for begin/end of std::ranges::take_view (#79085)

Add additional tests for `begin`/`end` of `std::ranges::take_view`.

In partial fulfillment of #72406.

[libc++] Qualifies size_t.

This has been done using the following command

find libcxx/test -type f -exec perl -pi -e 's|^([^/]+?)((?<!::)size_t)|\1std::\2|' \{} \;

And manually removed some false positives in std/depr/depr.c.headers.

The `std` module doesn't export `::size_t`, this is a preparation for that module.

[libc++] [test] Change a lot of free begin/end pairs to members. NFCI.

If you have a `begin() const` member, you don't need a `begin()` member
unless you want it to do something different (e.g. have a different return
type). So in general, //view// types don't need `begin()` non-const members.

Also, static_assert some things about the types in "types.h", so that we
don't accidentally break those properties under refactoring.

[libc++] Remove Lit annotations for unsupported GCC versions from the test suite

Since we officially don't support several older compilers now, we can
drop a lot of the markup in the test suite. This helps keep the test
suite simple and makes sure that UNSUPPORTED annotations don't rot.

This is the first patch of a series that will remove annotations for
compilers that are now unsupported.
