Check for iODBC and unixODBC with pkg-config in PDO_ODBC (#14963)

* Check for iODBC and unixODBC with pkg-config in PDO_ODBC

PDO_ODBC required that these backends had their path specified manually,
which was clumsy and contrary to how procedural ODBC checked it. This
adds a pkg-config based path to check for these backends that ignores
the 'dir' part of the flag, so i.e. --with-pdo-odbc=unixODBC should pick
it up from the correct location.

Generic and the special ibm-db2 usecase should be unaffected. The header
situation is unfortunately ugly, and has a workaround; this should also
be cleaned up.

* Move check for valid headers to after

* Use existing CFLAGS for PDO_ODBC header check

...instead of a separate funny variable. It does mean we have to save
and restore the value of CPPFLAGS, as AC_CHECK_HEADERS and friends rely
on that variable instead of CFLAGS.

* Move PDO_ODBC_TYPE to AC_DEFINE, simplify CFLAGS handling

The variable PDO_ODBC_INCLUDE becomes redundant, as is the CFLAGS
override for PHP_NEW_EXTENSION if we call PHP_EVAL_INCLINE in the
generic case.

* Use same variable names so evals can be combined

* Fix identation

* Suggested shell syntax cleanups

The include and lib dirs are looked for under 'dir'. The 'flavour' can be one
of: ibm-db2, iODBC, unixODBC, generic. If ',dir' part is omitted, default for
the flavour you have selected will be used. e.g.: --with-pdo-odbc=unixODBC
will check for unixODBC under /usr/local. You may attempt to use an otherwise
unsupported driver using the 'generic' flavour. The syntax for generic ODBC
support is: --with-pdo-odbc=generic,dir,libname,ldflags,cflags. When built as
'shared' the extension filename is always pdo_odbc.so]])
