Python: Unsafe input handling (#6003)

Browse Source 
### Motivation and Context

<!-- Thank you for your contribution to the semantic-kernel repo!
Please help reviewers and future users, providing the following
information:
  1. Why is this change required?
  2. What problem does it solve?
  3. What scenario does it contribute to?
  4. If it fixes an open issue, please link to the issue here.
-->
Implements dealing with unsafe content, by doing HTML parsing on
variables and function results.

Closes: #5889

### Description

<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->
Adds parameter `allow_dangerously_set_content` to:
- InputVariable
- PromptTemplateConfig
- PromptTemplateBase

The behavior is that if the flag is set to True on the template itself
(KernelPromptTemplate, Jinja2PromptTemplate or HandlebarsPromptTemplate)
the behavior is the same, no encoding is done on inputs.

Otherwise:
- variables are encoded by default, this can be switched off using the
InputVariables class for that variable.
- function output is encoded by default, this can be switched off using
the flag in the PromptTemplateConfig, this is not yet possible to do on
a per function basis.

This solution work as follows:
1. By default inserted content is treated as unsafe and will be encoded.
1. By default `HttpUtility.HtmlEncode` is used to encode all inserted content.
1. By default `HttpUtility.HtmlEncode` in dotnet and `html.escape` in Python are used to encode all inserted content.
1. When the prompt is parsed into Chat History the text content will be automatically decoded.
1. By default `HttpUtility.HtmlDecode` is used to decode all Chat History content.
1. By default `HttpUtility.HtmlDecode` in dotnet and `html.unescape` in Python are used to decode all Chat History content.
1. Developers can opt out as follows:
1. Set `AllowUnsafeContent = true` for the `PromptTemplateConfig` to allow function call return values to be trusted.
1. Set `AllowUnsafeContent = true` for the `InputVariable` to allow a specific input variable to be trusted.
1. Set `AllowUnsafeContent = true` for the `KernelPromptTemplateFactory` or `HandlebarsPromptTemplateFactory` to trust all inserted content i.e. revert to behavior before these changes were implemented.
1. Set `AllowUnsafeContent = true` for the `KernelPromptTemplateFactory` or `HandlebarsPromptTemplateFactory` to trust all inserted content i.e. revert to behavior before these changes were implemented. In Python, this is done on each of the `PromptTemplate` classes, through the `PromptTemplateBase` class.
- Good, because values inserted into a prompt are not trusted by default.
- Bad, because there isn't a reliable way to decode message tags that were encoded.
