Fixes: #5661

### Description
Fixes reflection of composite primary keys to maintain the correct column order in the MSSQL
and SQLite dialects.

Closes: #5662
Pull-request: https://github.com/sqlalchemy/sqlalchemy/pull/5662
Pull-request-sha: b568dec7070b4f3ee46a528bdf16fb237baade2a

Change-Id: I452b23cbf7f389c4a0a34cffce5c32498efe37d2

Added support for reflecting "identity" columns, which are now returned
as part of the structure returned by :meth:`_reflection.Inspector.get_columns`.
When reflecting full :class:`_schema.Table` objects, identity columns will
be represented using the :class:`_schema.Identity` construct.

Fixed compilation error on oracle for sequence and identity column
``nominvalue`` and ``nomaxvalue`` options that require no space in them.

Improved test compatibility with oracle 18.

As part of the support for reflecting :class:`_schema.Identity` objects,
the method :meth:`_reflection.Inspector.get_columns` no longer returns
``mssql_identity_start`` and ``mssql_identity_increment`` as part of the
``dialect_options``. Use the information in the ``identity`` key instead.

The mssql dialect will assume that at least MSSQL 2005 is used.
There is no hard exception raised if a previous version is detected,
but operations may fail for older versions.

It's better, the majority of these changes look more readable to me.
also found some docstrings that had formatting / quoting issues.

Improved support for covering indexes (with INCLUDE columns). Added the
ability for postgresql to render CREATE INDEX statements with an INCLUDE
clause from Core. Index reflection also report INCLUDE columns separately
for both mssql and postgresql (11+).

Bypass the test if the views are not being created.

Applied a sweep through all included dialects to ensure names that contain
single or double quotes are properly escaped when querying system tables,
for all :class:`.Inspector` methods that accept object names as an argument
(e.g. table names, view names, etc).   SQLite and MSSQL contained two
quoting issues that were repaired.

<!-- Provide a general summary of your proposed changes in the Title field above -->

### Description
<!-- Describe your changes in detail -->
- Update the test so it looks at computed_default_table instead of
  computed_column_table.
- Stop inspecting autoincrement; instead directly check for
  default/non-default values for the relevant columns.

Fixes: #5414
